They’ll have a tough time getting the thousands of Trump supporters out of a Bernie rally.
Dollars to donuts, Bolshevik Bernie will not handle it well.
I don’t think it would be a bad idea for Trump supporters to go to a Sanders or Clinton rally where they could listen, approve or disapprove of the comments as loudly as they like and leave peacefully. There is no need to behave barbarically to make a point. The numbers of Trump supporters should make that point very effectively.
