If one could be assured Trump would be a team player and support the nominee, no matter who it is one could feel better. But nothing in Trump's past shows he is a team player.Cowering from Trump now will make him look weak. The time he is needed is now.
His rise to the top in the GOP was by tearing down his opponent. We saw it in every debate. If he lost in the primary you know he would go third party and his focus would be on the Republican who beat him and the Democrat second. He would split the party and claim that was a win.
Trump is the reality. We know him and we know what he will do. He even got upset with DeSantis winning by 20 points and had to let us know DeSantis was ordinary and Trump had more Florida votes than DeSantis. Like any body cares. Except Trump only supporters, they care. So I say let him have 2024 and if he loses let him have 2028. Let him run until he dies if he can not win in 2024. It is the only way to save the GOP. You can not win without his supporters and no way you get his supporters as long as he is in the picture.
