If Moore did this stuff; it would hurt the GOP seriously. Most of those who are defiant are the independent surrender monkeys who helped Obama be elected. They haven't helped, they haven't helped noble causes, they sit back and complain about everything. They have no skin in the game.
Moore's response to dating teenage girls was "I don't remember but don't dispute it". Okay, so it is nothing illegal; but most males I think would admit, it would be inappropriate for a man over 30 to be dating teenage girls. This with Moore would be a bit of a circus, not good for the GOP.
