Just a placeholder till the convention when he will have dire (or is that Die or )medical problems and have to bow out. He will have Clinton 2.0
Wouldn’t surprise me, or combo Joe/Hilly, then Joe steps down if elected.
In either case I think The Donald with a successful end to this virus will go after either of them. Hopefully bolstered by a blistering Barr/Durham report to expose the deep state and some indictments.
