The specific context might be different, but I'm thinking a few British conservatives might feel a chill of recognition when they read this post:
Not that what one blogger thinks matters that much, but if Huckabee gets the nomination, I'm voting Democratic. It's not just an idle threat; I just won't vote for him and in fact won't even vote third party or stay home. I'll vote for the Democratic candidate, even Hillary. I won't be a party to selling out everything the party is supposed to stand for to a liberal ideology. If we're going to have eight years of liberal rule, I'd rather the Democratic Party be governing, so at least they can take the blame.
And, quite frankly, Hillary is to the right of Huckabee on most issues, if only because she's politically afraid to do the kind of crap Huckabee does and dream of doing at night. She couldn't afford to be as soft as Iran as Huckabee would.
