If the first Mrs. Biden learned of an affair Joe was having and he projected and gaslit her the way he often does to townhall questioners, I can understand her being upset and not paying attention when driving in traffic.
Perhaps the wife, the first white killed herself because Joe was having an affair with Jill. Jill’s ex-husband says that Joe and Jill met when he gave a fundraiser for a Joe in 1975. He says that Joe and Joel lied about when they met, were having an affair and that he found out when Joe wrecked the corvette Bill Stevenson, first husband, gave her. So it seems like they may have lied about everything from the beginning.
