I imagine that within the next couple election cycles the GOP will manage to marginalize the crazies and bigots. Then they can go back to only being as terrible as the Democrats.
I'm not entirely sure they can.
Let's say the GOP actually get sane on Gay Marriage, Abortion, and Guns? That they stop villifying immigrants and such?
Then what would they have to run on?
That you should be happy slaving away for the 1%ers, working harder for less money, hoping they don't ship your job to China?
The GOP should marginalize the crazies. But they also have to get back on the side of working people.
The rich are going to be just fine, really.
