Well yes, if one has rallies that attracts 50 or 100 it's easy to separate out those who disagree with you. But having a rallies of 10,000 or 20,000 is a different matter. And so far Trump has been remarkable considering the size of those crowds and the ferocity of the GOP and left against him.
Trump can still do very well in this campaign and tone down his rhetoric that misleads his attendees from believing they should do vigilante take downs of these thugs.
Trump is right about how these are “bad apples” and how he does not want people attending the rallies to be hurt.
But he is wrong to suggest that he wants to hit them or suggest that his supporters should hit them or be violent toward them.
It is a recipe for disaster and it is exactly what these jacobins want.
