The dead tend to become martyrs, which is just about the last thing we need. We need people to come to their senses and see him for what he is, which is a con man and charlatan, with no dignity, decency, or empathy. And we need his shame to be pervasive enough to render Pence, Ryan, and McConnell useless for standing by him. In my opinion, there's a tipping point where Republicans will throw him under the proverbial bus. For most sane people, that point has come and gone, but not for the GOP.
