It is not entirely about whether Huckabee can win. It is about whether republicans in the remaining states want McCain as their nominee. They haven’t even voted yet. Until McCain reaches the winning number, their votes should still count. Many voters in those states want another option, they want Huckabee or anyone other than McCain. See Kansas. So just slow up and wait until your candidate actually wins enough support from real GOP voters in the remaining states.
He isn't my candidate. I never like McCain and am almost afraid of the prospect of him in the White House. (for many reasons but mostly because of his famous temper)
Regardless I think Huckabee is embarrassing himself and should just go away.
