I agree, if the Republicans could dump, they'd be wise to. But they had their chance, but stuck to their guns (no pun intended). This is their mess, they own it. They will suffer from it for a while. Pretty much the GOP has lost any chance they had at making inroads into the young person market, the black vote or most likely any other minority vote. And I'm sure they're going to lose the female vote too.
Basically, the GOP has decided to stick with their base. Angry white men and angry racist white men.
They deserve this, and they will have to own it and own up to it if they want to survive over the next few years.
But they don't have to do too much, since this is the democrats we're talking about. They'll fuck this up somehow.
