McCain needs only 20% of the remaining delegates to take the nomination on the first ballot.

Not a done deal, at all, for a candidate that can't break out of the 30's percentile in red and purple states.

Huck won in Iowa and the south. There are only a few more winner take all states, and they aren’t in the south. Every other state will be apportioned. Huck cannot win enough votes to make up the difference. And you assume all those who were inclined to vote for Romney would vote for Huck. It isn’t going to happen.
