Why vote for a law-and-order candidate who can provide neither law nor order???
In 2016, Trump was the challenger, not the incumbent.
What makes people think riots help an INCUMBENT who just shouts about riots and is completely ineffectual in actually stopping them??
Trump can't offer ANY of that.
Logic and reason lead to the same conclusion, of course, but you don't need logic or reason to instantly see what Trump is. It's plain as day.
