IF, and of course that's a big IF, the dems really want to get rid of Biden *before* the unusually scheduled early debate (quite a coincidence, hey?) all they have to do is skip the meds they gave him for this year's SOTU address, or whatever they gave him for the debates in 2020, or whatever drug it is they give him when he has to be relatively coherent for a couple of hours. (and then we don't see him for three days!)
If they have the balls to do that, the entire nation will see, sadly, the President of the United States crash and burn on national TeeVee.
Thank you Demonrats.
I'm not going to predict they'll do that, but they are quickly running out of time / options for replacing him on the ticket.
