It's not quite Hatfield vs. McCoy, but the feud between Rahm Emanuel and Howard Dean is very real, and potentially a very serious problem for Democrats this November.

Jim VandeHei reports on the continuing schism between Dean and members of the House Democratic caucus, led by Emanuel, who are gravely concerned (and more than a bit upset) that Dean isn't putting together a strong enough turnout operation focused on the most competitive races this fall:

Democratic Congressional Campaign Committee Chairman Rahm Emanuel (Ill.) -- who no longer speaks to Dean because of their strategic differences -- is planning to ask lawmakers and donors to help fund a new turnout program run by House Democrats. He recruited Michael Whouley, a specialist in Democratic turnout, to help oversee it.

"I am not waiting for anyone anymore who said they were going to" build a turnout operation, Emanuel said. "It has got to be done."

While the anger toward Dean is real and growing, as VandeHei reports later on this is almost certainly a preemptive strike on the part of Emanuel and Pelosi aimed at setting up Dean to be the fall guy should Democrats fail to win back the House. It's absolutely going to work, too, since Dean has exposed himself by stubbornly sticking with his '50-state strategery.'
