“Such warnings would really tick off Brandon who will dig heels and stubbornly refuse to quit.”
President Trump talking about the planned switcheroo just might prevent it from happening for the reason you said.
If Trump can force Biden to remain on the ticket (by predicting switcheroo) that serves his (Trump’s) interest too.
Hard to image someone weaker than Biden to run against.
It’s not the number of people voting for Biden we have to worry about, its the number of ballots that materialize for Biden. He was a weak candidate in 2020.
Except maybe Kamala.
