President Trump is attempting with considerable success to cut the crime rate in the federal District of Columbia. Its constitutional federal status permits him to do. He then threatens to do something similar in deep blue mega-cities across the nation.
It is well-known the President doesn't always mean 100% of what he says, he regularly floats trial balloons to judge their acceptance and political potency. My guess is his threat to bring the national guard and a bunch of different federal cops to blue cities is one of those "balloons."
His real strategy? He cleans up crime and homelessness in DC, then points to his success and asks why the Democrat mayors of large cities aren't doing what he did. After all, he's proved it to be possible, doable, and popular with voters.
There is nothing quite so powerful as a well-publicized object lesson.
