Wow.

You gotta check out this new Frank Rich op-ed to understand how the Clinton campaign tactics may be dividing and, in the end, destroying the Democratic party. The title says its all: "Next Up for the Democrats: Civil War."
It centers on the (intentionally) divisive claim by the Clinton campaign that "hispanics don't vote for black candidates":

It wasn’t an accurate statement, historical or otherwise. It was a lie, and a bigoted lie at that, given that it branded Hispanics, a group as heterogeneous as any other, as monolithic racists...The real point of the Clinton campaign’s decision to sow misinformation and racial division, Mr. Rodriguez concluded, was to “undermine one of Obama’s central selling points, that he can build bridges and unite Americans of all types.”

On reinforcing that (false) division for future races:

The question now is how much more racial friction the Clinton campaign will gin up if its Hispanic support starts to erode in Texas, whose March 4 vote it sees as its latest firewall. Clearly it will stop at little. That’s why you now hear Clinton operatives talk ever more brazenly about trying to reverse party rulings so that they can hijack 366 ghost delegates from Florida and the other rogue primary, Michigan, where Mr. Obama wasn’t even on the ballot. So much for Mrs. Clinton’s assurance on New Hampshire Public Radio last fall that it didn’t matter if she alone kept her name on the Michigan ballot because the vote “is not going to count for anything.”

And on the hope for negotiating a compromise before the convention:

But does anyone seriously believe that Howard Dean can deter a Clinton combine so ruthless that it risked shredding three decades of mutual affection with black America to win a primary?

A race-tinged brawl at the convention, some nine weeks before Election Day, will not be a Hallmark moment. As Mr. Wilkins reiterated to me last week, it will be a flashback to the Democratic civil war of 1968, a suicide for the party no matter which victor ends up holding the rancid spoils.
