Because of the the recent controversy I think rather than having been born in the U S to qualify as President you have to have been a President that died here.
So I think I would go with any of the first five, Lincoln, Reagan and possibly Kennedy. I am not sure where we should dig first.
Since that most likely won't happen, I will be voting for the Republican whoever he is.
Since I hope but don't expect Ron Paul will be the candidate I believe it or not, think that will end up being Gingrich. I am guessing VP candidate will be Rubio or Cain, possibly Paul Ryan with Allan West as a long shot.
I also think Hillary will be the opposing candidate, not Obama; so take all the above with the requisite grain of Salt.
