There's one city conspicuously missing: Minneapolis
It absolutely should be on any list of anarchic cities, with slashed police budgets and spiking crime. But it's not, and nothing I've seen suggests a good reason for leaving it off.
Which means Trump is playing politics, trying to flip Minnesota by not pissing off residents in a swing state before an election. The other cities are in states he has no intention of winning. That's pretty crass.
(Not surprised the media isn't calling him out, though, it's kind of hard to say "peaceful protests" and then your gotcha! moment is describing how police cuts lead to soaring crime in a city.)
