We are probably witnessing the beginning of the end of both Trump and Desantis’s aspirations, if DeSantis had any, for high office
DeSantis won’t win the primary and Trump won’t win the general
It is a horribly divided GOP
DeSantis won't win the 2024 primary, mainly because Trump will have salted the earth on that one. However, if he keeps his powder dry, and bides his time until 2028 - which will give him plenty of time to build up the political capital he will eventually need as president - then I don't see why Trump's tantrums spell the end of DeSantis' own political aspirations.
They do spell another four years of destruction and stupidity for this country, but that would not be DeSantis' fault if he chose to stay out of a race that has been poisoned by Trump.
