I fear that will not be a sufficient deterrent. Between the Romney's of the world, Senators being shown the contents of their Deep State security files, and oceans of money for those who vote to convict, I think there is a real risk of the Senate selling out the country.
As much as I appreciate your points I still don’t think they will turn on Trump as this would effectively finish off the gutless GOP for good. Its a fake party that has done nothing but deceive us for decades. It should have been abandoned long ago in favor of a new party that actually stands for something.
