It's an old trick in the book to call someone (whom you dislike) crazy: Does away with need to argue rationally, as there is no arguing with (or about) "crazy".
They've done so with almost any "dictator" they disliked (e.g. Gaddhafi etc).
From what I see, these guys, relying on this "extremist" political spectrum (and arguments) are gonna lose so hard in November, makes me lol now already ….. but of course one wouldn't wanna be hasty with celebrating before the fat Lady has sung ….
