I agree with your comments...IMO, President Trump is wisely waiting for the current impeachment fiasco to end before announcing any definitive plans. I will support him whatever he decides to do. But I hope he will turn most of his attention to backing primary candidates, in his mold, to oppose Rinos. And, IMO, leading election reform efforts, especially in Pennsylvania, Georgia, Michigan, Wisconsin, Nevada and Arizona, is also a crucial role for him.
If he could manage it, I would like to see him treat Rat leadership with disdain; but not waste too much of his his time with verbal responses to their treachery and ignorance. A cryogenic plate full of revenge in the form of younger, Trump style primary candidates is just what the likes of Liz Cheney, Kinzinger etc. need crammed down their throats.
