I think Biden was the “known sacrifice” to an election that the democrats knew they had no chance at all of taking - until their Wuhan Flu succeeded - THEN, they began to think they had a chance as the economy tanked and was held underwater for a half-year.
But by then it was too late, and the field had been artificially narrowed to Biden and Sanders - who the party could not tolerate as an outsider to their insiders. (By the way, Hillary must really be decrepit if her name is not even allowed to come up at all!)
The riots were convenient, but burning cities by democrats does not inspire anybody to vote democrat but those who enjoy burning cities. And news readers on ABCNNBCBS.
To an extent I think you are right. They may have seen Trump as vulnerable with the China Virus-—but that’s only half the equation. They didn’t then, and still don’t have a candidate at the national level who can match him.
I don’t see it in 2024 either.
