I do also, but I've heard it said a few times from different people who have interviewed him or been around him in small group situations. And it's been said to caution people who continue to underestimate his appeal.
Those are the same people that say he's highly religious (specifically Christian). They're a bizarre set.
It's the cult leader aura.
For those infected he's articulate and smart.
For those outside the cult he's a demented bumbling fool.
