This is NOT another 4 year election. The risk is simply too great to allow things to fall back into enemy hands… Therefore….
Trump catches Covid-19 and "passes away."
Pence takes over and gets put on the ballot.
All mail-in ballots are recalled, forcing the entire country to vote in-person.
Folks are overwhelmingly reluctant to change horses mid-stream and Pence is easily reelected.
Trump isn't really dead. Whether he surfaces again or just retires on a private island in French Polynesia is another matter altogether.
I put the chance of this happening around 1%. But who the fuck knows? Stranger things have happened.
