That works if he drops out AFTER the election. If he drops out before the election, there is no way people are going to go vote for him and Trump wins an EC landslide. It’s too late. Joe cannot drop out, and the media will make sure the the story is treated just like the title of this thread suggests. They will call it a fabrication, fake, a Russian disinformation operation, desperation, debunked, etc.
But if he were to be replaced, prior votes will still count even if future voters object to voting for his replacement.
