Sad, but true. If he were truly as “wise” as his cult following believes, and truly loved America, was a true conservative, and truly wanted MAGA to win, he’d read the writing on the wall and gracefully retire from running for president, be mostly quiet and try to act like an elder statesman. He would gain respect and influence that way. History would lionize him for that. But no ... he has to act like this. It seems he can’t help himself.
Trump knows that his true power over his army (which is what he's trying to develop) are these very mean tweets. It's why he spent all of 2021 setting up his new website, instead of doing what he promised and raised $250M to do - investigate and implement election security.
Trump knows that website, full of his devotees, is his true source of power. Whenever he posts something on Truth, they all fall down in adoration. He only posts a portion of those same posts over on Gab, or Gettr, where they get a much different treatment.
He uses these mean tweets to try to build his larger than life image as a fighter, when in TRUTH (pun intended) he's often just using Alinsky tricks to cling onto power.
