Agree about the rubes on this board, but they are all 65+ and their brains are calcified. However, there are Republicans who will follow the MTG model and their 'come to Jesus" moment won't be one of mental clarity, it will be political opportunism, because they will (correctly) sense that people have reached the unmistakable conclusion that Trump is nuts, and they want to capitalize on the sentiment, while being on the right side of history.
It won't have anything to do with doing the right thing for their country.
