This will happen. Trump supporters will carry a stigma. They will deny they supported him at some point down the road. It will be an embarrassing part of their past and one they will deny. This is going to happen.And I do mean expelled. The Republican party is a private organization. Trump is no conservative. He isn't even a real Republican. His most prominent supporters, at all levels, must be expelled.
Defeating Donald Trump isn't enough. His supporters must pay the price too. For that, we'll need Democratic help.
