... Democrats lean more PC than the GOP (new slogan: "Talk English!"), and know they're supposed to care about this stuff even if they privately really don't. So will that sort of pressure and expectation influence caucus goers? Think of Catholic John Kennedy essentially daring protestant West Virginia to prove they weren't bigoted in the primary by voting for him over Hubert Humphrey in the 1960 primary. ... Will folks who sincerely support a white male candidate stand up instead for Barack or Hillary, for fear of accusations of prejudice? I don't see how Iowans will feel like we'd "prove" anything by caucusing for Obama. We're not much accused of being old-South style racists in national Democratic circles; we're just blamed for being very very very very white. Guilty as charged, pass the tuna fish casserole. My guess is the uniqueness of Obama's story and his much-vaunted charisma will make the race thing a non-factor.
