While I think that there are grounds for impeachment, I"m sure that, based on your records, you would rather follow Trump over your own constituency or perhaps even your own conscience. I would therefore hope that he will hang himself in such a manner that you feel compelled to step forward. Unfortunately, I don't think there's much hope for that at this time. I expect that most Republicans are waiting to see which side of the fence will be the most popular before they are willing to come forward.
