COCONUT GROVE - It's hard to keep up with the flood of commentary from the left about Bill Clinton's increasingly negative role in the Democratic primary. Bob Moser of The Nation pens a particularly harsh assessment:

After Saturday's primary, this Tar Heel can do nothing but offer a big, deep bow to the Democrats of South Carolina. Not because I was particularly rooting for Barack Obama over John Edwards--but because of these fine folks' rejection of the Clintons' gutter politics. The majority of white Democrats, in a state where the Democratic Party was so long the organized mob enforcing Jim Crow, repelled the Clinton campaign's unspeakably vile attempt to paint Barack Obama as some kind of coke-dealing, slumlord-pimping cousin of Al Sharpton--and their equally vile assumption that Deep South whites, whether they're Democratic or Republican, can be manipulated by coded racial divisiveness in 2008 the way they were in 1968. Or, to add a bit more vileness to the mix, their assumption that they could make South Carolina blacks believe that one of their own would be "unelectable" by definition.

Frank Rich warns of the perils of Billary in this morning's New York Times. Even avid Clinton supporter Josh Marshall is having his doubts, saying he has been feeling "a mounting sense of unease verging into disgust with Bill Clinton's increasingly aggressive role in the campaign over the last couple of weeks."

With Caroline Kennedy's endorsement this morning, and this tease by Mark Halperin suggesting Uncle Teddy's isn't far behind, there's a growing sense that the Democratic establishment is getting ready to throw the Clinton era into the dustbin of history. Of course, the Clintons will not be shoved aside easily, if at all.
