Markos of Daily Kos:

I don't care if someone is a moderate, liberal or conservative Democrat. You could be any of those things and still be a partisan Democrat. The DNC chairmanship is a partisan position. As such, Martin Frost is grossly unqualified for the position.

...To be clear, I don't care what Democrats might have to say to get elected in deep red districts. But if you spend a year distancing yourself from the Democratic Party and sucking up to Bush, Hastert and Hutchinson, then you have no business trying to run the Democratic Party.

He's right. Martin Frost ran for re-election in his Texas District by praising Republicans, as if he were one of them, and hiding his Democratic party affiliation. You can watch this CBS newspiece , featuring one such ad, thanks to Ana at Anatopia. Note that the word "Democrat" is nowhere to be found.
