As Dana just noted, this seems to be emerging as a two-man race between McCain and Huckabee on the GOP side. We were joking earlier in the office about a Huckasurge, but he does appear to be making a comeback tonight, having claimed Arkansas, West Virginia, Georgia, and Alabama. The pundits keep noting that Huckabee is taking home the South, while McCain's wins thus far are pretty solidly in the Northeast, lending further fodder to rumors of a possible McCain/Huckabee ticket as a means of strengthening McCain's cred in the South.
