Apparently there was a plan at the Chicago rally to rush the stage and beat Trump (possibly to death). There was about 200 Soros people stationed in all the right places to overwhelm security on all sides and the venue had made sure that regular CPD cops where not allowed in to do security.
Trump was tipped off by the CPD which is why he canceled the event.
Which means there are plans to kill him, and some are intended for implementation.
Maybe that is why Ted, Jeb, George Will, Kasich and others say that Trump will NOT indeed MUST NOT be the nominee.
I suspect them all of being co-conspirators to murder.
