Sadly, this clip is too short to give the full flavor of yesterday’s circus. Jill was at some White House gig “honoring” NEA chief Randi Weingarten when Joe “unexpectedly” appears, gives his standard, “I’m Dr. Biden’s husband, Joe”, joke, and then proceeds to the podium to address an uncaring crowd while Jill repeatedly tries to pull him away. Anyway, here’s a snippet. If he weren’t President of the United States, his mental condition would be merely sad; as it is, it’s also alarming.
