100% surety that the Dems bounce Biden. They play hardball, they know he can’t win, they will not sit this one out.
Biden was the useful meat-puppet in 2020 as Covid provided lots of cover for his decline.
But they cannot do that now (even though he just tested positive for Covid)
Democrats want power more than anything. A last minute switch with the right candidate will tighten up the polls so the fraud cannot be overcome.
Given that a recent report shows Harris doing better against Trump than Biden, I think they will go that route.
