At a rally today in Dayton, a protester jumped a barrier and ran at Trump onstage, surprising him, before the Secret Service could escort him out (the protester, not Trump.) Trump's response: "I was ready for him, but it's much easier if the cops do it."
I think Trump is showing what a panty-waist he is, and that he has no leadership ability. His abandonment of his supporters yesterday, in essence playing one faction against the other- a common power tactic- is the worst move he could have made. It's becoming more and more difficult to imagine him being elected. He may be able to buy control of the GOP, but I don't think he can buy the presidency.
