Under ordinary circumstances, I'd agree. But we're talking about the MAGA King here.
No, he's an incumbent president, you disingenuous person. No one seriously challenged Donald Trump in the 2020 primary when he was the incumbent.
Why do you feel so Trump is so entitled to the nomination? I think he (and DeSantis and anyone else) has to earn it. It's not a Hillary Clinton circa 2016 coronation.
