I dunno. It goes without saying that the Xian right and the knuckle draggers will eat it up like flies on shit. However, Palin's AIP membership and yahoo-ism doesn't play well in places like Grand Rapids, where conservatives are conservative. It's OK with the East coast old-money crowd -- what do they care as long as they have a free hand & low taxes -- but the less cynical conservatives won't like it. These are the old-church protestants & Catholics + the Main street petit-bourgeois & small town bourgeoisie. Even McCain might be a little too wild for these folks. There's a class anxiety among this strata that makes it difficult for them to identify with Palin, so i don't think the identity politics necessarily works out positively for them.
Looking at how this plays out in terms of states and electoral votes, i could see Palin being a drag on the ticket in Michigan, Wisconsin, Iowa & Minnesota, but boosting it in Indiana and Missouri. In other words, a net loss, at least in the upper Mississippi valley.
And this just in:
US election: Conservative pundits caught criticising Palin
The criticisms seem fair.
