I saw that guy. He looks kind of bothered but seems to shake his head like "I can't believe he said that but he did." 
You have to remember that Donald trump is rebel sexy for republican white guys. They live vicariously through Donald. He's their (cartoon) superhero. Donald is obviously aware of the role he's playing in the imagination of this segment of the American populace. He's playing the poor saps for all they're worth, something he thinks he's very good at. But they're too high on Donald crack to notice he's playing a role. Is it more disturbing or funny? It depends on how you look at it.
