Those things that you mention are most certainly the kinds of things that many Republicans won’t like.
But, you have to be well known.
Ron Paul is well known, as is Palin, Gingrich, Romney, and Bachmann (barely).
Palin is the best known and the best liked, and would have to be seen as the front runner.
But those 5 are the only 5 who are well known enough to win.
