First, Kamala... No one wants Kamala to be POTUS. No one. none of this happens until Kamala is replaced. And that’s not likely to happen before the GOP takes control next January, and (depending on the nominee) won’t get thru the Senate prior to that.
Second... why would the GOP remove Biden? It appears to be the Dems considering a 25th Amendment thing, not the GOP. Why replace Biden/Harris with a team that might be much stronger in 2024?
Third... Who? Who do the Dems have that would be acceptable enough to get thru the Senate for either VP or POTUS? The Dems wiped out all of their non-elderly non-liberal folks when the voters took revenge for Obamacare....
The only path I could conjecture is if they bump off Clarence Thomas and insert Kamala onto SCOTUS.
Then VP Booty-Gig would move up with a “retirement” of Biden.
If Hairass become president look for a “National Unity” veep. They’d want a vp that would not run in 24. Can you say VP Romney?
