As for e-s, that's just how he rolls. He just became my new best buddy here at FR. He'll tell you that you're completely wrong, missed everything, don't even know your own name, and then scoot away when you try to talk to him about it, the little scamp! But he'll come back around and chuck a random insult your way, that's just the little prize that he is. He's been a little ray of sunshine since 1998. He's got life all figured out and everybody else is just an idiot in his world. Can you imagine how much fun he'd be at parties?
Rush was so transparently in the tank for Cruz during the '16 primary, it was embarrassing. He was also pointedly rude to callers who supported Trump - interrupting them, laughing under his breath at them, cutting them off, making funny noises as they spoke, etc.
Meanwhile, Cruz callers were treated with real respect and camaraderie.
It was shameful.
