I follow a handful of legacy mainstream news sources fairly closely which some would say are liberal. I'd never heard of the guy. That might say something about how social media, which I don't use, is shaping political opinions in a major way.

I see DJT has assumed it was someone from the radical left, and in a position of leadership and in an effort to quell the divisions has said, "...and we just have to beat the hell out of them."
