There is no rational reason for any supporter of the President to do this. Therefore the remaining possibilities are that the perpetrator is an irrational supporter of the President or somebody opposed to the President.
(We will assume, for the sake of argument, that absolutely nobody in the country is neutral about the President. Even if this is not true, it feels true)
Bingo. And while there may be — surely are — irrational supporters of the President, I'd assert those types wouldn't have the dinero and intelligence to pull these off all within a couple of days. I predict a couple of losers with right-wing stuff on their social media pages eventually will be arrested — because part of the mastermind’s plan will have been to leave some “right-winger” holding the smoking gun. (And, yes, it wouldn't be hard to find some loser fan of Trump's to take 5K in exchange for doing the last of 50 things on the To Do list to pull this off.)
