 One CNN panelist on Sunday said Biden needs to smile more. That's the ticket. The real question is which Biden will show up. Will it be the angry old man so amped up on something or the other that he yells for 90 minutes as he did during the State of the Union address? Or will it be the dazed and confused Biden who mumbles and bumbles through an event? Will it be old yellow or sleepy Joe? We'll find out Thursday night. Folks, don't underestimate this.
