Deletion of Joe Biden presidential campaign, 2020

Comment: as  per nom.  This subject doesn't even exist except in an off-handed comment Biden made on December 5 at an unrelated event, and a follow-up response that he'd like to run but he knows there's no way to tell how things are going to go in 4 years.  This is the only real subject of this article: a single comment and follow-up question.  The first 4 sources cover this same couple minutes with the press.  A couple of the sources claim outright that he was joking.  The other 9 sources are just older background, unrelated to 2020
