I don’t think he’ll be seen or heard from past March, 1st or 2nd week. The dementia is far outpacing any meds they’ve been pumping into him at this point, and he’ll be cursing and screaming so much at the drop of a hat or even at things that aren’t even there, the next thing anyone sees (that’s even watching) is CommiemalaHarris being sworn in with some CCP Manifesto.
IMHO they will try to prop him up as long as possible. Compare this mess to the debates and you can see how far he has declined.
