Huckabee and Brownback would have some issues, but have enough conservative cred to back track a bit from boneheaded things in the past and be forgiven. Paul I did not include, because he is a libertarian.
Hunter has no backtracking to do, and he never, ever mealy mouths an answer.
Living in San Diego with the Mexican border around 20 miles south from where I am sitting, anyone for amnesty
is the same as voting for a liberal democrat.
