I'm really hoping, and I'm sure they are, that Trump's team is really gearing up for the possibility that somehow Joe really shows up for the debates.
Maybe several quips like "You know I'm really glad the old Joe showed up tonight, you never know what you're going to get. Watching some of your scripted interviews go off the rails I'm glad to see you can still pull it together occasionally"
It even works if he shows up as sleepy Joe too, just insert a "I was really hoping the old Joe..." instead and hit him with it repeatedly.
One way or another, I hope Trump is going to take a few jabs in that direction just to see what his response is. Do we get a push up contest challenge?
If Biden challenges him to a pushup contest Trump should say sure go first Joe. If he gets down and does pushups Trump should point to him and say that's sad what someone can get him to do, can you imagine him at the negotiating table?
