I don't think he'll win the nomination. I think most are kind of over the schtick. Him taking heat for the midterms and pissing off Murdoch won't help.
I think most have moved on to DeSantis. But we're still wayyyy early of course.
Honestly if I’m going to give Trump the benefit of the doubt (which I am not inclined to do) you could argue that this is exactly what he wants. Trump ran in 2016 as an anti establishment guy, which is pretty hard to do after you are elected president. Now he’s looking more and more like an outsider again.
Would be a desperate move, for sure, but I think the play is ultimately banking on the fact that any Republicans with a voice are also spineless, which I think is definitely true except for maybe Romney.
