I would agree, but even if they stopped his ego would get in the way and he’d be jealous that others are stealing the spotlight. People close to him have basically confirmed that he is jealous of, and potentially threatened by, Ron DeSantis.
Also worth pointing out that “pro-Democracy” organizations like The Lincoln Project and Meidas Touch have essentially been begging for him, who they’ve said is the biggest threat to democracy, to run again and baiting him to do as such, in addition to trying to get him injected into various races. Last year there was a poll that came out from a conservative conference which showed DeSantis ahead, but Rick Wilson and some of the other LP bros had tweets trying to encourage Trump to run again. They’re doing this because Trump is very beatable in a General Election and has severe limitations, as he consistently underperformed down-ballot Republicans in suburban counties. DeSantis doesn’t alienate these voters who historically vote Republican and split their tickets in 2016 and 2020, so they want Trump in the race to take him out.
