Trump Plans to Cram His Entire Legislative Agenda Into Days 96-99

Mother Jones

<!DOCTYPE html PUBLIC “-//W3C//DTD HTML 4.0 Transitional//EN” “http://www.w3.org/TR/REC-html40/loose.dtd”>

Did Mack Sennett ever make “The Keystone Cops Go to Washington”? No? No matter. That’s what it feels like right now.

Let’s see if I can do justice to our current legislative follies. For starters, it appears that we’re going to get health care, tax reform, and infrastructure all in one week. Why? I guess so that President Trump can say he got going on all of them in his first hundred days. Which totally doesn’t matter and Trump couldn’t care less about it. But he released a truly comical list of all his accomplishments anyway. Not that he cares. But anyway. Let’s move on.

Health care: The House Freedom Caucus has allegedly agreed to an amendment to the previous House bill—the one that crashed and burned last month thanks to the HFC’s opposition—that now makes it acceptable. They haven’t actually said so in public yet, but maybe tomorrow they will. Maybe. Basically, it allows states to opt out of the essential coverage requirements of Obamacare. Except for Capitol Hill, that is. Members of Congress will continue to get every last thing on the list. And there’s no change to pre-existing conditions except for one teensy little thing: insurance companies can charge you more if you have a pre-existing condition. How much more? The sky’s the limit, apparently. Does $10 million sound good? In practice, of course, this means that they don’t have to offer coverage to anyone with a pre-existing condition.

Tax reform: It turns out the Treasury Department really was taken by surprise on this, so Wednesday’s announcement will be little more than the same stuff Trump released on the campaign trail. Corporate taxes get cut by nearly two-thirds, to 15 percent. Ditto for “pass through” corporations like, oh, just to pull an example out of the air, The Trump Organization. There will be no offsetting spending cuts. There will be no border tax. There will be nothing much for the non-rich except a modest change to the standard deduction. There will, of course, be no details about which deductions and loopholes, if any, Trump plans to plug. It will be a gigantic deficit buster. And just for good measure, it’s probably literally unpassable under the Senate’s rules.

Infrastructure: In a laughable attempt to get Democratic support for his tax bill, Trump plans to add infrastructure spending and a child tax credit to it. The problem is that Trump’s infrastructure plan is little more than a giveaway to big construction companies, and his child tax credit—designed by Ivanka!—is little more than a giveaway to the well off. In other words, instead of one thing Democrats hate, the bill now has three things Democrats hate. I’m just spitballing here, but I’m not sure this is how you make deals.

This is lunacy. The barely revised health care bill probably won’t pass the House, let alone the Senate. Tax reform is just a PowerPoint presentation, not an actual plan. Plus it’s such an unbelievable giveaway to the rich that even Republicans will have a hard time swallowing it. And the infrastructure stuff is DOA. It will almost certainly be opposed by both Republicans and Democrats.

This is like watching kids make mud pies. I guess that’s OK, since this is all terrible stuff that I hope never sees the light of day. Still, I guess I prefer even my political opponents to show a little bit of respect for the legislative process.

Basketball Is the Worst Sport Ever (In Its Final Two Minutes)

Mother Jones

<!DOCTYPE html PUBLIC “-//W3C//DTD HTML 4.0 Transitional//EN” “http://www.w3.org/TR/REC-html40/loose.dtd”>

A few days ago I was channel surfing and ended up watching the final tedious few minutes of a basketball game. It was at the point where the losing team was doing the intentional foul thing in a last-ditch effort to make a comeback. “Does that ever work?” I muttered. Now I have an answer:

Nick Elam, a 34-year-old middle school principal from Dayton, Ohio…has tracked thousands of NBA, college, and international games over the last four years and found basketball’s classic comeback tactic — intentional fouling — almost never results in successful comebacks. Elam found at least one deliberate crunch-time foul from trailing teams in 397 of 877 nationally televised NBA games from 2014 through the middle of this season, according to a PowerPoint presentation he has sent across the basketball world. The trailing team won zero of those games, according to Elam’s data.

What a waste. Elam has a provocative proposal about how to fix this, but it’s far too radical for the NBA to consider. After all, the league’s boffins won’t even consider changing the intentional foul rule or limiting timeouts. If they can’t bring themselves to make modest changes like that, what are the odds of ever doing something serious about the final two minutes of basketball games, which are widely considered the most tedious 20 minutes in all of sports?

On the bright side, at least basketball’s final two minutes are still better than soccer’s tie-breaking shootout—which is basically just a fancy way of flipping a coin. Personally, I’d make them keep playing until the players start collapsing on the pitch—and then leave them there until somebody finally scores a goal. Maybe that would motivate them.

White Men Liked Mitt Romney Better Than Donald Trump

Mother Jones

<!DOCTYPE html PUBLIC “-//W3C//DTD HTML 4.0 Transitional//EN” “http://www.w3.org/TR/REC-html40/loose.dtd”>

Here’s a fascinating comparison of the 2012 and 2016 presidential elections via Stuart Stevens. I’m not sure what the source is—someone’s PowerPoint presentation, perhaps—but I assume the data was transcribed correctly. Here it is:

This is based on one poll, and it’s pre-convention. Still, it sure explodes a lot of myths about Donald Trump. He’s doing worse among white men than Mitt Romney and much worse among white women. He’s doing slightly better among the middle-aged, but far worse among the elderly. And he’s doing better among blacks.

On the non-surprising front, he’s doing far worse among Latinos. Obama won them by 44 percent, while Clinton is winning them by 62 points. I wonder why?

This doesn’t show how Trump is doing specifically among blue-collar white men (those with no more than a high school diploma), but I wonder if he’s really as popular among this demographic as everyone thinks? Or, in the end, is he just going to perform in a pretty standard Republican way, but just a bit worse?

Pop Goes The Digital Media Bubble

Mother Jones

<!DOCTYPE html PUBLIC “-//W3C//DTD HTML 4.0 Transitional//EN” “http://www.w3.org/TR/REC-html40/loose.dtd”>

You don’t always hear the bubble burst. Often, it’s more a gradual escaping of air, signaled by nothing more than the occasional queasy feeling you bat away: One house for sale on the block, oh well. Two, three—maybe just a robust market? Five, six, seven—and suddenly everyone’s underwater and the sheriff is at your door.

That’s kind of how it’s feeling in the digital media business. For a few years now, investors have been pouring money into online news with the kind of fervor that once fueled the minimansion boom. But in the past year, the boarded-up windows have started showing up: The Guardian, which bet heavily on expanding its digital presence in the United States, announced it needed to cut costs by 20 percent. The tech news site Gigaom shut down suddenly, with its founder warning that “it is a very dangerous time” to be in digital media. Mobile-first Circa put itself on “indefinite hiatus.” Al Jazeera America, once hailed as the hottest thing in bringing together cable news and digital publishing, shut down and laid off hundreds of journalists.

Pop.

And it’s been getting worse. As the New York Times’ John Herrman put it, “in recent weeks, what had been a simmering worry among publishers has turned into borderline panic.” Mashable, which had made a big investment in news and current affairs, laid off dozens of journalists and pivoted to a new, video-heavy strategy. Investor darling BuzzFeed fought reports that it had slashed earnings projections by nearly 50 percent. Salon laid off a string of veteran staffers. Yahoo put its core business, including its news and search features, up for sale.

Pop. Pop.

Here’s the thing: It was not hard to see this coming. For years now, smooth-talking guys (yes, mostly guys) with PowerPoint decks have offered up one magic formula after another to save the business of news. Citizen journalism—all the reporting done by users, for free, with newsrooms simply curating it all. “Brand You”—each journo out there on her own, drawing legions of followers to her personal output. (Even Andrew Sullivan couldn’t make that work.) Viral headlines—every news shop Upworthy-ing its way into the Facebook swarm. Aggregation, curation, explainer journalism, explainer video, branded content, text bots, video, branded video, branded virtual reality video…each fueling the hope that here, at last, was the way to make news profitable again. A whole class of future-of-news pundits made a living pontificating about how “legacy media” were getting their lunch eaten by digital-native startups.

And the investor money kept coming. BuzzFeed, Vox, Vice, Fusion, Mic (not to mention their 1stGen cousins Salon, Slate, Huffington Post, and Gawker)—for a while they all were too fast to fail, hiring Twitter-famous names out of established newsrooms, rolling out sexy technology systems, and exploding watermelons on live video. As Josh Topolsky, a veteran of digital media (most recently at Bloomberg) wrote the other day, “I can tell you from personal experience over the last several months, having met with countless investors and leaders of media companies and editors and writers and technologists in the media world that there is a desperate belief that The Problem can be solved with the New Thing. And goddammit someone must have it in their pitch deck.”

But while a ton of great work has come (and continues to come) out of all the New Things, none of them have answered the burning question of how to pay for journalism—especially the public-interest, watchdog, feet-to-the-fire kind that democracy needs to function. For one thing, all the big new digital shops today employ, between them, a few thousand journalists—compared with the ten-thousand-plus laid off in the great retrenchment of 2007 to 2010. For another, like virtually every other hot property across the internet, digital media startups are better at growing than at showing a profit. And since a profit is what the people supplying those giant piles of cash are ultimately looking for…

Pop. Pop. Pop.

Mother Jones is a nonprofit—precisely to avoid this fate. Tax-deductible donations from readers give us stability.

Remember when Chris Hughes put The New Republic up for sale earlier this year? His letter to TNR staff subtly blamed the very same people it was addressed to: “I will be the first to admit that when I took on this challenge nearly four years ago, I underestimated the difficulty of transitioning an old and traditional institution into a digital media company in today’s quickly evolving climate.”

Bullshit. “Transitioning” was not The New Republic‘s main challenge. Refusing to work on, with, and for the internet was once a pervasive problem in news organizations, but while vestiges of that still linger, it is no longer what keeps publications from succeeding financially.

What keeps them from making money now is that online advertising pays pennies. (Actually, a penny per reader is pretty good these days—CPM, or “cost per thousand” ads, is often far less than half that.) And there are a ton of people competing for those fractions of a penny—including Google and Facebook, which collectively pulled in a whopping 85 percent of new ad spending in the first quarter of this year. The only way to make ends meet in that environment is to turn up the fire hose of fast and cheap content or rent your pages out to native advertising (sorry, branded content).

Look at it this way: A reporter doing even modestly original work might produce five stories a week (and that’s not allowing for anything more than a few phone calls and a couple of rounds of editing per piece). If each of those stories gets, on average, 50,000 readers, and each of those page views generates 0.01 cents (again, a very generous rate), you’ll end up grossing $2,500 a week, or $130,000 a year, with which you’ll have to pay the reporter and her editor, their benefits, web tech, sales and ops staff, taxes, insurance, electricity, rent, laptops, phones…

And this calculus assumes a brutal pace of hour-by-hour filing and publishing, with journalists constantly looking over their shoulder at the traffic numbers. (When a New York Daily News editor was fired last week for dropping attributions from columnist Shaun King’s stories, he noted that he was expected to process 20 stories from five reporters each day.) And the kind of digging that an investigative story requires—months of research and reporting, plus fact-checking, editing, and maybe multimedia production—forget it. The math just doesn’t work.

So what does? At MoJo, the answer is: You.

From the very beginning, 40 years ago this year, our newsroom has been built on the belief that journalism needs to be untethered from corporate interests or deep-pocketed funders—that the only way a free press can be paid for is by its readers. This can take a few different forms: subscriptions, donations, micropayments, all of which we’re experimenting with. It can be something the audience is forced to do (via the paywalls you’ll find at the New York Times or the Wall Street Journal) or something they choose to do, as in public radio.

At Mother Jones, we’ve gone the latter route: Our mission is to make our journalism accessible to as many people as possible. Instead of requiring you to pay, we bet on trust: We trust you’ll recognize the value of the reporting and pitch in what you can. And you trust us to put that money to work—by going out there and kicking ass.

Because of your trust, we can choose which stories we go after, rather than chasing the spin du jour. We can look where others in the media do not. We can, as our colleague David Corn puts it, get off the spinning hamster wheel and dig deep.

And we can do it without fearing that some corporate overlord will pull the plug. Remember what happened when casino magnate and Republican megadonor Sheldon Adelson bought Nevada’s largest daily newspaper, the Las Vegas Review-Journal: as the sale was being negotiated, reporters were mysteriously tasked with digging up dirt on a judge who’d antagonized Adelson. Then the newsroom was told to back off covering the biggest story in town—their boss. This was a paper where a columnist had already been hounded into bankruptcy by Adelson over a few words. (We faced a similar attack recently from another billionaire upset about our critical coverage of his past.) Your support is what keeps Mother Jones‘ journalists from having to fear that kind of intimidation and control.

If you’re a regular reader of Mother Jones, you’ll have noticed that we’ve been in the equivalent of a pledge drive this month: We need to bring in $175,000 by Saturday to stay on track. This is something we do three times a year, and it’s the most important way we raise money to pay for everything we do.

But we’re not crazy about these monthlong fundraisers, and maybe you aren’t either. So we’re looking at ways to make it easier (“frictionless,” as they say in the tech world) for you to support the journalism you believe in. One of our big initiatives is an online sustainer program, where readers agree to give us a bit of money every month. That could make a big difference for our stability: Just 1,200 more readers who value our reporting enough to pitch in $20 a month would get our “sustaining” revenue up to $50,000 a month, or $600,000 every year. If that’s an option for you, it would be a big help.

Become a monthly donor.

Make a one-time gift.

Meanwhile, that $175,000 by the end of the month? It’s not some arbitrary goal, but the cold, hard number required in our budget to keep our reporters on the beat. In the first 26 days of this month we’ve raised about 75 percent of that, so we need $45,000 in the next four days. But that’s how these campaigns typically work: Everyone waits until the last minute to pitch in.

If that’s you, remember that ultimately this is about something bigger than MoJo. If we’re going to have a functioning democracy, we’ll need a press that can turn over rocks, and the days of that being financed by deep-pocketed media companies are drawing to a close. The new moguls are in the technology business, not the journalism business. And while some of them say wonderful things about journalism, money talks—and right now, the money is saying “pop.”

Here’s the Defense of Unsalted Pasta Water That Darden Won’t Make Itself

Mother Jones

<!DOCTYPE html PUBLIC “-//W3C//DTD HTML 4.0 Transitional//EN” “http://www.w3.org/TR/REC-html40/loose.dtd”>

Over at Vox, a virtual water cooler for the world’s most pressing problems, Matt Yglesias tells us that Darden is fighting back against charges that it has mismanaged Olive Garden. But he’s unimpressed with their PowerPoint deck:

The entire Darden counter-presentation has nothing to say about salting the water. And to be clear, this is a 22 slide presentation. They had plenty of opportunity to explain themselves, apologize, or deny it. Instead, they’re just keeping quiet.

Here at MoJo, an entirely different virtual water cooler for the world’s most pressing problems, I don’t know anything about cooking pasta. However, one of my readers claims he does. So here’s the defense that Darden has declined to offer on its own:

I acknowledge that salting the water is a common and recommended practice for both pasta and dried beans, but this practice has the effect of toughening the outer surface of both pasta and beans during the cooking process. If you wait to add salt until after the cooking is completed the texture of the boiled food will be more tender. This does not mean it can’t be “al dente,” which refers to the structure of the complete noodle (or bean), just that the skin or surface is not tough. Try it.

So there you have it. Feel free to discuss this critical issue in comments.

Year-End Whining Gets Results!

Mother Jones

<!DOCTYPE html PUBLIC “-//W3C//DTD HTML 4.0 Transitional//EN” “http://www.w3.org/TR/REC-html40/loose.dtd”>

Normally, my blog whining produces no results worth mentioning. But last month was different: two, count ’em, two of my whines got results. This is easily a new personal best.

First up: I complained bitterly that Charlie Stross’s newly revised Merchant Princes series was available in Britain but not in the US. I understand why the publishing schedule for the physical books might be off in the future, but why not release the e-versions? Well, the estimable Patrick Nielsen Hayden of Tor Books heard my lament and sprung into action. As a result, digital versions of these books will be available in the United States next Tuesday, January 7. Details and links here.

Second: I expressed surprise that no one was talking yet about Thomas Piketty’s new book, Capital in the 21st Century. Sure, it’s only available in French at the moment, but there must be at least a few economists who read French and have something to say about it. Right? Well, Brad DeLong, who (a) reads French, (b) also happens to have on hand a manuscript of the English translation, and (c) has read the PowerPoint notes for a lecture Piketty gave based on his book, provides us with a synopsis of Piketty’s findings:

  1. As growth rates decline in the Old World (Europe and Japan), we will once again see the dominance of capital: a greater proportion of the wealth of society will be held in the form of physical and other non-human-skill assets, and inheritance and position will matter more and individual effort and luck less.
  2. In fact, given relatively high average rates of return on capital and thus a large gap vis-a-vis the growth rate, wealth concentration is likely to reach and then surpass peak levels seen in previous history as the superrich become those who started wealthy and benefitted from compound interest and luck.
  3. America remains an exceptional puzzle: it looks, however, like it is headed for an even more extreme distribution of wealth than is the Old World.
  4. Remember, however: the evolution of income and wealth distributions is always political, chaotic, unpredictable–and nation-specific: not global market conditions but national identities rule wealth distributions.
  5. High wealth inequality is not due to any “market failure”: this is a market success: the more frictionless and distortion-free are capital markets, the higher will wealth inequality become.
  6. The ideal solution? Progressive global-scale wealth taxes.

There’s much more at the link, including the complete set of slides from Piketty’s talk. Or you can wait until March when the English translation comes out and everyone dives in.

I am excited that my end-of-year whining has produced such stunning results. All that’s left is to figure out if this is just a coincidence, or if my whining has somehow become more effective lately. Perhaps I should whine more to find out?

Al Gore: Gutless media caves to climate deniers

Al Gore: Gutless media caves to climate deniers

CGIAR Climate

Al Gore

Should the media be giving as much ink to fossil fuel-funded shills as it gives to the hundreds of climate scientists who collaborated on reports being published by the United Nations?

As coverage of the Intergovernmental Panel on Climate Change’s latest assessment report reaches fever pitch, some mainstream media outlets are treating climate science as if it were just an abstract political debate. They are falling into the trap of treating it as a mind-numbing to-and-fro argument with no right and no wrong — instead of something produced through good old-fashioned scientific rigor.

That pisses a lot of people off. One of them is Al Gore.

Gore, the former vice president who should have been president but instead used Powerpoint to put climate change on a lot of regular folks’ radars, is not shy about using his outsized soapbox. He was blunt in sharing his reflections Friday during a talk at the Brookings Institution. Here are some choice quotes, as transcribed by The Hill:

“Here in the U.S., the news media has been intimidated, frightened, and not only frightened, they are vulnerable to distorted news judgments because the line separating news and entertainment has long since been crossed, and ratings have a big influence on the selection of stories that are put on the news.”

“And the deniers of the climate crisis, quite a few of them paid by the large fossil fuel polluters — really it is like a family with an alcoholic father who flies into a rage if anyone mentions alcohol, and so the rest of the family decides to keep the peace by never mentioning the elephant in the room. And many in the news media are exactly in that position.”

“They get swarmed by these deniers online and in letters and pickets and all that if they even mention the word climate, and so they very timidly, they get frightened and they are afraid to mention the word climate.”

“Their purpose is to condition thinking and to prevent the consideration of a price on carbon. It’s just that simple.”

That simplicity is worth keeping in mind the next time you encounter a media outlet playing the old “on the one hand, on the other hand” game with climate science.

Leaked EPA document raises questions about fracking pollution

Leaked EPA document raises questions about fracking pollution

William Avery Hudson

The EPA isn’t looking too hard at what Cabot Oil & Gas Corp. is up to behind this fence, or anywhere else.

The EPA doesn’t seem very interested in finding out whether fracking pollutes groundwater. The latest indication of this emerged over the weekend in the Los Angeles Times.

Residents of the small town of Dimock in northeastern Pennsylvania have long been convinced that Cabot Oil and Gas Corp. was poisoning their drinking water by fracking the land around them. In July of last year, the EPA announced that although water from some local wells contained “naturally occurring” arsenic, barium, and manganese, the agency was ending its investigation there without fingering the any culprits.

Now we find out that staff at a regional EPA office were worried about the role of fracking in polluting the town’s water, but their concerns appear to have been ignored by their bosses.

An internal EPA PowerPoint presentation prepared by regional staffers for their superiors and obtained by the L.A. Times paints an alarming picture of potential links between water contamination and fracking. And it reinforces the perception that the EPA is giving a free pass to the fracking industry, perhaps because natural gas plays a key role in President Obama’s quest for “energy independence” and an “all of the above” energy portfolio. From the L.A. Times article:

The presentation, based on data collected over 4 1/2 years at 11 wells around Dimock, concluded that “methane and other gases released during drilling (including air from the drilling) apparently cause significant damage to the water quality.” The presentation also concluded that “methane is at significantly higher concentrations in the aquifers after gas drilling and perhaps as a result of fracking [hydraulic fracturing] and other gas well work.” …

Robert B. Jackson, professor of environmental sciences at Duke University, who has researched methane contamination in the Dimock area and recently reviewed the presentation, said he was disappointed by the EPA’s decision.

“What’s surprising is to see this data set and then to see EPA walk away from Dimock,” Jackson said. “The issue here is, why wasn’t EPA interested in following up on this to understand it better?”

The EPA confirmed the authenticity of the PowerPoint presentation, but dismissed it as “one [on-scene coordinator’s] thoughts regarding 12 samples” that was never shared publicly because “it was a preliminary evaluation that requires additional assessment.”

The Natural Resources Defense Council puts this latest retreat by the EPA into some context:

Unfortunately, what appears to have happened in Dimock is just the latest in a larger, troubling trend we’re seeing of EPA failing to act on science in controversial fracking cases across the country. Instead, the agency appears to be systematically pulling back from high-profile fracking investigations.

First, in March of 2012—without explanation—EPA abruptly withdrew an emergency order it had issued two years earlier against Range Resources Corporation after the agency found nearby natural gas production operations from the company had likely caused methane and toxic chemical contamination in Parker County, Texas drinking water supplies. … [T]he Associated Press reported that a leaked confidential report proved that EPA had scientific evidence against Range, but changed course after the company threatened not to cooperate with the agency’s ongoing national study of fracking. AP also reported that interviews with the company confirmed this. When asked to explain its actions in light of all of this, EPA’s silence has been deafening.

Then, in late June 2013, EPA made an equally abrupt and unexplained announcement that it was abandoning an investigation into a high-profile drinking water contamination case in Pavillion, Wyoming. …

Now it seems the third shoe drops in Dimock — the latest in what was a triumvirate of highly anticipated federal fracking-related investigations.

Maybe the EPA has forgotten what its middle initial stands for?
