I have come to the conclusion that Republican pols today are not, by and large, descended from the public faces of the Bush family or Reagan, but from the backroom dealings in the school of Karl Rove, Lee Atwater, Richard Nixon, and Dick Cheney. They want to win. That's it. It doesn't really matter how.
For all their Christian trappings, if asked, "For what is a man profited, if he shall gain the whole world and lose his own soul? Or what shall a man give in exchange for his soul?" they might readily respond with the words of Vince Lombardi:
Winning isn't everything. It's the only thing.
