A coworker had a tin foil hat conspiracy plot. Biden potus for a week and resigns, Harris potus for a week then resigns do pelosi can take over. I wouldn’t put it past the democrats but if they do, no one that isn’t a hard core lefter would ever vote blue again.
I honestly doubt pelosi would even want the presidency, she couldn't do as much damage that way and she'd have a term limit.
I suspect this is the case for MANY politicians who hold solidly uncontested seats in the senate and house.
