Even if you sympathize with some aspects of his agenda, you have to admit that the way he goes about doing it is really utterly incompetent. Like, Obama himself has hinted that Islam itself has deep structural problems, and this sort of attitude and the natural incentives he has in not having further terrorist attacks on his watch, likely led to significant restrictions. Of course he put on a public face. Trump it looks like will always have a hard time getting any restriction, no matter how valid, because he has no reservoir of goodwill.
