This is an important revelation that unmasks the rabid tribalism of contemporary politics.  
Two guys who are essentially the same, just wearing different shirts are rabidly hated by the supporters of the other side, and adored by their supporters - for the same damn reasons.  It all comes down to hyper-partisan tribal BS. "He doesn't wear the same colour shirt as me, so he's scum!" 

Hyper-partisanship is ruining what is left of our democracy, and is largely responsible for electing two completely unfit leaders in Trudeau and Trump.
