i think you are underestimating how good trump is at this. it's not something that would work for many other people (but other people could probably do other things that wouldn't work for trump but that are currently dismissed as not standard operating politicianing).
what a sad end to #nevertrumpism, btw. back in the day, when trump rallies included daily beatings and likeable young politicians like rubio seemed poised to pick up the pieces, it felt so promising. and now we're here hoping the voters in the stupidest state of the union will vote for the least likeable politician in the world in order to stave off death for at least one more week.
