I disagree. I have studied the demographics on a few states and it appears to me that he is stuck where he is because of these issues. They limit him as much if not more than they buoy him.
Even if he is elected, he can't succeed in this issue.
Again, my problem is not that you find his position wrong, I do as well. It's that it would comprise your one "fear about McCain." McCain's threats to liberty are greater and more realizable than Huckabee's. Huckabee as VP would not make any difference to me. Hell, I'd probably prefer him as President over McCain, though the preference would not be enough to make me support him.
Cool. So you are against the FDA?
Very much so, on some issues.
