Given that McCain needs only about 20% or so of the remaining delegates to get the nomination, and these are proportional races for the most part from here on out, it would take a total collapse of the McCain campaign to not get the nomination. I respect Huckabee continuing to fight (unlike all the other candidates that folded prematurely — and I’m especially talking about Thompson and Romney here).
Actually I’m wrong.
According to this blog there are only 775 delegates left to win. In that case Huckabee still has an outside chance.
