John Heilmann helps Robert Reich drop a bomb on the Clinton campaign :

Reich insists that the endorsement does indeed come as a surprise — to him. As we chatted in Washington, where Reich had come from Berkeley, where he teaches, to give a speech and meet with some Democrats on Capitol Hill, he explained that, despite the criticisms he's made of the Clintons ("I call it as I see it"), he had planned to refrain from offering an official backing for Obama out of respect for Hillary. "She's an old friend," Reich said, "I've known her 40 years. I was absolutely dead set against getting into the whole endorsement thing. I've struggled with it. I've not wanted to do it. Out of loyalty to her, I just felt it would be inappropriate."

So what's changed? I asked Reich.

"I saw the ads" — the negative man-on-street commercials that the Clinton campaign put up in Pennsylvania in the wake of Obama's bitter/cling comments a week ago — "and I was appalled, frankly. I thought it represented the nadir of mean-spirited, negative politics. And also of the politics of distraction, of gotcha politics. It's the worst of all worlds. We have three terrible traditions that we've developed in American campaigns. One is outright meanness and negativity. The second is taking out of context something your opponent said, maybe inartfully, and blowing it up into something your opponent doesn't possibly believe and doesn't possibly represent. And third is a kind of tradition of distraction, of getting off the big subject with sideshows that have nothing to do with what matters. And these three aspects of the old politics I've seen growing in Hillary's campaign. And I've come to the point, after seeing those ads, where I can't in good conscience not say out loud what I believe about who should be president. Those ads are nothing but Republicanism. They're lending legitimacy to a Republican message that's wrong to begin with, and they harken back to the past 20 years of demagoguery on guns and religion. It's old politics at its worst — and old Republican politics, not even old Democratic politics. It's just so deeply cynical."

To have tossed aside a 40 year-old friendship and business relationship is beyond serious. It's a brutally honest repudiation from a man who has become a sort of oddball superstar in the academic wonkosphere with such ponderings as Is Capitalism Always Good For Democracy? and the nature of Supercapitalism. Especially since Reich happens to be from ... ahem ... Scranton, Pensylvania.

In other words, it's gonna hurt and send another wave of "Judas" accusations a la Bill Richardson. Stay tuned. At 1:00pm he's dropping the endorsement on his blog.
