Ted Cruz is a principled conservative. Much more than Bush, Rubio, Walker, and Paul. Dr Carson is another consistent candidate with tons of common sense. Watch Trump choose Cruz or Carson as running mate.
Christie, Kasich, Perry, Fiorina, Jindal, Santorum, Huckabee etc are irrelevant because they have no chance to win nomination. Although Jindal is perhaps the most consistent conservative who has never back tracked on any position.
