He could be a top vice presidential pick for Sen. John McCain himself, but Newt Gingrich thinks that Mike Huckabee and Florida Gov. Charlie Crist are better bets. "My hunch is that he will probably choose Charlie Crist," says the former House speaker, describing the guv as popular and a close McCain ally. "The other possibility, which will be equally interesting, is Huckabee." Gingrich also spelled out how McCain can win: Call the fight with Sen. Hillary Clinton "machine politician versus the citizen reformer." Or dub Barack Obama "the most left-wing politician ever."
