I don't know. I sympathize with the way the guy felt but that kind of shit is likely to benefit Trump. It's pretty clear that most Trump voters aren't very smart and have a ridiculous double standard about things today... "Jews will not replace us" - fine people. Angry guy throws water - dangerous gang member. Trump's 3000 lies - "well they all lie" : Obama says "if you like your doctor" - unforgivable. Trump Foundation is a sham - that's ok. Clinton Foundation does good shit - crime family.
I guess my point is, Trump is hurting his own people economically, make it easy for them to throw him out.
