I think you're underestimating the growing disillusionment of MAGA voters. He lost, when he said he had it in the bag. He then flubbed a coup, which in the end only resulted in hundreds of MAGAts going to jail, with hardly a word of thanks or encouragement from him. Many of them have found themselves alienated from their families and wondering what it was for, because after eight years of Trump they haven't seen a single thing from him that he promised them.
The white supremacist douche brigades support him because he's all they've got, but everyone else is more wobbly than they have ever been. They fear "the libs", but with four years of Biden now and none of their fears realized in that time, the bite has gone out of even that particular dog.
Now is the time when we should be reaching out to them, encouraging them to come back into the fold of mainstream America. Let them realize that they've slipped to the fringes and are in danger of truly being left out.
