Just to take a reality break...
1. The senate will likely stay GOP based on the fact that Doug Jones is toast in AL, and the 4 toss-ups all won't go democrat.
2. The House will likely swing back to the GOP because the 31 seats the dems won in 2018 in Trump districts will most likely swing back to the GOP since Trump has a 95% approval rating among Republicans
3. So even if Joe ekes out a presidential win he won't be able to do much damage.
More likely Trump will win re-election, just based on Joe being so old and obviously has dementia.
If this scenario does happen the GOP House will need to start impeachment hearings in Feb 2021.
