He's finished, anyway, so all this really makes no difference. After the insane email he sent Rep. Wasserman Schultz, there is no doubt he means what he says. During the last election, he even used rhetoric about going to his opponent's house, which is clearly crazy as well.
The insane email that called Wasserman Schultz unprofessional? That sounds like an accurate description to me. Anyway, this is obviously just rhetoric you can throw to the crowd, you know, kind of like how Republicans like to throw Grandma off cliffs?
