Here is a fantasy:
Leaky Leahy from VT leaves the Senate (now 50 Gop / 49 Dem) due to health issues.
Biden spends the next few months going up to the 2022 election working on getting Harris out.
No VP in office
2024 Election is a GOP landslide
House meets and nominates Trump as Speaker
Senate does not confirm anyone to VP
House opens RELENTLESS investiggations into the the Biden Presidency
Cabinet members are told quietly that they either play ball or go to prison
Biden is removed via 25th amendment for his declining mental health
... again, no VP
Trump becomes President
... dreaming, I know but still ....
Any port in a storm....................
