Perry will probably be convinced to drop out after South Carolina, if he doesn’t do well.
I can see Santorum staying in, if he scores well amongst the Evangelicals and Catholics, so it might take some deal making to get him to get out.
I had to cringe when he was called out for voting for mandatory trigger locks and closing the ‘so called’ gun show loophole. Then he lied and said the NRA supported that.
There is no way gun owners will let that slide, he is toast.
