Please don't typecast liberals or conservative to support your claims.   EX:  95% of Roseburg did not protest his arrival, therefor the President is love by 95% of Roseburg.

As long as Trump had his own troops in the room, there was nothing to start conflict.   When somebody let in the real world, there was lot's of conflict.     I don't know who started it.    

Why do you think Republicans require a pledge of fidelity to the Republican party for admittance into their TV 'town hall' meetings.    Trump only wants to preach to the choir.   The world beyond TV and high fences isn't as tidy as Trump wants it to be.

*I've spent a lot of time poking at politics from both parties.   I'm sure you can find such 'planned supportive'rally's' from Democrats.
