No, it's up to the local and state police to provide security at the rallies.
It's up to the secret service to protect Trump.
He should proceed with all planned rallies and let the pros do their jobs.
And, yes, there will be violence and grand theater.
He'll be at the top of the news every hour while white people watch and seethe.
It was obvious there was not enough security (police etc) in Chicago. And then the police were saying don’t harass the protesters. It was right for Trump to cancel. If 200 protesters would have stormed the stage, there would not be enough secret service to handle it and obviously CPD don’t give a damn.
After March 15 it will quiet down considerably if Trump wins Ohio and Florida. The agitators are pulling out all of the stops until then, and that includes assassination, both by character and by force.
