Donald Trump will be assassinated by Reince Priebus manipulated into sAvInG dEmOcRaCy!! by trying to restore his lost honor as the chair of the RNC when Trump initiated his takeover.
At the moment I'd say Trump is a lock for the primary ... his closest competitor is a Trump impersonator with stunted social skills after all ... and after winning the primary he will be frozen out and ignored by media outlets and lose in 2024.
DeSantis will wait until 2028 to throw his hat in.
