This AP 
article on the upcoming trial in Portland about deploying the National Guard goes into details about excuses for a crackdown that will be used in other cities by any US administration, at any time, from now on for such a move against officials who stand up for their rights.
If the control freaks can get away with it now.
Trump is all about precedent, nothing more.  And the socialists and other left-wingers know it and are waiting.  Some people here are wise to the threat, too, as is that North Carolina Congressman mentioned earlier, but I wish more Trump supporters would wake up and smell the tear gas.
As for Portland itself, after they broke out the frog costumes I decided that it's not in my universe, let alone my state.  What they need up there is grown-ups, not boots on the ground, and that has probably been true for a long time.
It's a nice city -- reminds me of Birmingham, but with a huge river (the Willamette, not the Columbia; the two rivers meet a little farther downstream).
But the last time I was up there, in 2015, I saw so much urban dirt and dysfunctionality and, as mentioned, just the two extremes: snobs and homeless camps/broken people.
All the "middle" folks have fled to the suburbs and washed their hands of the urban decay, apparently, though they seem willing enough to bask in Portland's "quirkiness" and snobbery about personal wealth (which is a widespread malady out here anyway).
Little, if any, real soul.
But they don't deserve to get a gut punch from Trump (who could have turned this state red in 2020, if he had looked beyond Portland and been willing to work at recognizing and organizing his many Oregon supporters that year; apparently even then he had a different agenda).
