Well played, Trump. There were a lot of places Trump could have a rally in Illinois, but he chose this one in order to have this confrontation. A reality tv star's one job is to successfully call attention to themselves. Trump just got a lot of free publicity that answers the accusations that Trump fans are the violent ones. He could have bought ad time explaining how he is not a violent racist. Or he could do what he did, have his opponents revert to type in front of the cameras.
Trump is a supreme strategist...always a few steps ahead of the morons who organized this protest.
I have a theory that Trump knew what was going to happen if he spoke in that area and knew he would get shut down and he did get shut down and now the media is showing the protestors being the asses and long term it might harm them, agree or disagree.
