The 90% theory is just about what happened in 2020 if not for all the cheating they did to carry that mental catastrophe to the oval office. All you have to do is look at Trump's rallies. He commands huge gatherings of people from all walks of life. You cannot erase what he did and everyone knows it. Niki IS the Swamp. She is doing their bidding. DeSantis Did their bidding. The only reason he dropped out was because it was getting comical.
DeSantis was pushed out so there would only be one candidate concentrating fire on Trump. 54% to 46% looks way better than 54% to 25% to 21%.
Trump must be stopped at all costs, and the Republicans in name only are big into the push.
Haley can be disposed of in the general election. The biggest fear is that Trump will get so many votes that the cheating to beat him will be blatantly obvious. And beat him they will, but at what cost.
Remember Hillary cautioning voters to not panic right after the election, that they would "find the votes".
