If you’re in the “Not Trump” camp, who’s left realistically except Ted Cruz? His right-wing competition, i.e. Rick Perry and Bobby Jindal, seems to be going nowhere. He’s raised far more money than anyone expected he would, so he’s likely to be competitive deep into next spring at least. He’s well positioned in Iowa, South Carolina, and the “SEC primary” thanks to his evangelical cred. And as the staunchest conservative in the top tier, he’s a natural draw for righties who dislike Trump because they believe (correctly) that he’s a phony conservative.
