Back to where this all started, I think Zeke is right. She was not chosen for her ethiocal stands, her conservative ideals, her position on RKBA or Roe v. Wade. She was chosen because she was a woman that would appeal to the hard core right, many of the RINO's, and some of the women supporters of Hillary. The fact that some us us find her to be a good choice doesn't mean she was chosen for thise reasons...
I think she would be the best president of the bunch of them. McCain has the right temperment but seems inclined toward civility above all else. No one knows much about BHO except he is black and wants change. Biden is well known for his ultra left views.
Palin is well regarded among conservatives and libertarians, but not real well known outside that group.
I agree she was chosen for political reasons, including being a woman. Political calculations are a big part of politics.
