trump always needs a rival, someone he's feuding with. Rosie, whoopie, jeb, rubio, megyn kelly...
he's not happy unless he's got some enemy he's wrecking. He cannot just run on policy, he's crap on policy. He runs on "seriously, I cannot wait to see what this nutjob does next..."
he promised to cover legal bills of any supporter that whoops on a protester. Then he acted all shocked when 1) supporters started assaulting protesters, and 2) protesters started getting in faces to spurn such attacks.
What in the world did he think would happen? exaclty that. This is a calculated move to get his rallies in ohio on the front page, about 2 days before the big Ohio primary which will effectively make him the nominee, if he wins it...
this is all planned and we shouldn't just fall for it. but we will.
