AT DAILYKOS, more blowback on the idea of Hillary going negative:
Hillary’s backers reportedly are planning to fund a Swift Boat-style 527 assault on the favorite for the Democratic nomination, Barack Obama. If we act now in a concerted way, perhaps we can head off Hillary’s Swift Boats before they slime the "change" candidate and tear down his winning coalition. I don’t think Hillary can win this anymore, but she could damage Obama’s chances in the general and hurt a wide mandate for progressive action.
Even the threat of going negative is hurting Hillary with Obama supporters. I'm not surprised. She wouldn't be so constrained if Edwards were the frontrunner.
