Too much credit? For four years we heard "No... he couldn't possibly... he wouldn't dare... oh. He did." Some people spoke up, they were dismissed as hysterical, Trump written off as a buffoon.
You give him too little credit; he's not a buffoon. He sowed chaos for four years, created an alternative reality for millions, is seen by many of his followers as literally sent by god to destroy pedophile democrats, and without batting an eye, he incited an insurrection that damn near succeeded. Seventy-four million Trumpers may be idiots, but beware the power of idiots in large groups. And those idiots are represented in Congress by politicians wielding a lot of power, and who will gladly use the idiots for personal gain. Ignore at your peril...
