I think MAGA could have a life of its own...if Trump would allow and encourage that.
I think there WAS a good way forward from here; with MAGA being kept going and Trump trying to strategize something new in terms of messaging and collaboration.
But insulting the GOPs biggest stars, and Musk, pretty much kills any hope of a different strategy involving more collaboration.
Trump works for his ego. I have no problem with him having a big ego. But to the extent he gets into insulting and name-calling he mostly displays his ego is actually quite fragile, and his emotional intelligence isn't nearly so high as I would have hoped.
