While I can fully agree that he hasn't been "presidential" in the traditional sense, (he's a bombastic troll), that isn't actually required to do a good job as president, which he's mostly been doing.
And besides, aren't those on the left all about tearing down old traditions and making way for new ways of doing things?
Also, I see you're still conveniently ignoring the part where he invited them to come back after they had successfully implemented their suggested policies.
