I vote for Huckabee is now an almost pure vote for a contested convention. Huck is unlikely, even if almost sweeps the next 20 some odd states, to collect the delegates needed to win. That said, he can collect enough delegates to block McCain . . .
What do you plan to do when he drops out and endorses McCain? They will cut off his $ now since his purpose for being in the race has been accomplished, so he isn’t going to stop anybody from getting the nomination if he wanted to do so.
