"He may be the most threatening and frightening and menacing presidential candidate in modern life, and yet, in person he's almost soothing.... If onstage he calls people names, more privately he has only good, embracing things to say about almost everybody. (For most public people I know, it is the opposite.) He loves everybody. Genuinely seems to love everybody — at least everybody who's rich and successful (he doesn't really talk about anyone who isn't). Expressing love for everybody, for most of us, would clearly seem to be an act. But with Trump, it's the name-calling and bluster that might be the act. I offer that there are quite a number of people in New York, some we know in common, who are puzzled that the generous, eager-to-be-liked and liking-everyone-in-return Donald has morphed into a snarling and reactionary public enemy, at least a liberal enemy. This, I suggest, might be a source of the continuing dialectic — or to some, wishful thinking — that he does not necessarily believe what he says."
From "The Donald Trump Conversation: Politics' "Dark Heart" Is Having the Best Time Anyone's Ever Had," by Michael Wolff in The Hollywood Reporter.
Also interesting: Trump has a refrigerator in his Beverly Hills home that has nothing in it but bottled water and pints of Haagen Dazs... and Trump eats a whole pint of vanilla at 11 p.m. and tells Wolff not to put his water bottle on the fabric ottoman.
