I wonder how many early primary states have similar figures for Democrats who don’t like Hillary… and whether that puts a ceiling on her level of support…

Like Edwards and Obama, nearly everyone planning to attend the Democratic caucuses has an opinion about Clinton, the third-place finisher in the poll. But overall, those opinions aren’t quite as positive. About two-thirds have favorable feelings toward her and nearly one-third look upon her unfavorably.

That’s the latest Des Moines Register poll, which has Edwards 29, Obama 23, Clinton 21 and Richardson 10.

Among Republicans, it’s Romney 30, McCain 18, Rudy 17, Tommy Thompson 7, (Anybody else wondering if some of that is people who are thinking of Fred?), Brownback 5.

Among those expected to attend the Ames Straw Poll August 11, it’s Romney 34, Rudy 16, McCain 15, Tommy Thompson 8, Brownback 6.
