If McCain extends an olive branch to moral/social conservatives by picking Huckabee as his VP, he will definitely get my vote. Otherwise, he will get my vote, but not with any enthusiasm.
BTW - I DO think McCain will be the nominee and WILL pick Huckabee as his VP to shore up the value voting base of the GOP.
Republicans don’t get my vote by default either, I vote solely on issues. Unfortunately, I’m very secular and believe in Evolution. Three candidates in this matter don’t believe in evolution, which scares the hell out of me. I will probably vote third party.
