Ha! That's a new twist. One I have not considered before.
I cant take credit for this theory, my oldest daughters husband is a history major and he told me about it. Trump knows he will never get enough votes to win outright, so knowing that, he is going to use the same tricks he uses in the boardroom. If you dont like how the numbers add up, change the formula.
This whole fake fighting between Trump and DeSantis is nothing but a show, Trump will get all of his believers votes, DeSantis will get the average Republican vote and Biden (or the Democrats pick) will get the rest. After nobody gets the required electoral votes, the House will vote according to the rules and they will elect Trump. And dont worry, DeSantis will know exactly what is going to happen and will be part of it.
The only thing that changes this is if the Forward party actually takes off, that will let Trump run as a Republican with the same end result.
