Sorry to keep harping on this, but here's yet another poll (this one from Time/CNN) that shows the "unelectable" Howard Dean running as well against Bush as the other top Democrats -- or, to be precise, somewhat better:

Bush over Dean 51% to 46%

Bush over Lieberman 52% to 46%

Bush over Kerry 54% to 43%

Bush over Gephardt 53% to 44%

Bush over Clark 53% to 43%

Bush over Edwards 53% to 43%
