Just because a person withdraws for good reason does not mean they were pressured into it out of fear of a felony conviction. You are grasping at straws. Biden was torpedoed by his own party, an inevitable consequence of his pathetic incapacity.

But you are incorrect that "we can never know for certain." The claim is absolutely verifiable as certain, if true. Declarations of declining re-election are documented in the news. And felony convictions are documented by court proceedings.

Personal conviction is not "knowing." F^at Earthers have that kind of attitude and they are as wrong as orange on a zebra. (The more credible supposition is that someone "had a talk" with the candidate, and they were convinced it would go better for them if they stepped aside.)
