Signs of a McCain-Huckabee alliance multiply. Ambinder at the Atlantic reports on the West Virginia GOP caucuses (which Huckabee won):

But sources say that representatives for John McCain called many of his reps in WV and asked them to vote for Huckabee...in order to thwart Romney on the second ballot.

Ron Paul's people also seem like they may have swung for Huckabee, too, in WV.
