Byron Donalds has shown up to support him...I don't cosinder him "fringe".
Cruz showing up in support of Trump??? He's fighting for his seat and he's already been ridiculed and mocked for supporting Trump because of how Trump beat up his character, ridiculed his wife and called his father an assassin. Cruz has publicly commented in his defense recently and has been met with ridicule.
Trump attacked DeSantis in much the same way, he has stated that he will campaign for Trump, but .... that has also been met with some reservations by his supporters.
Trump has created much of his own problems. No, I don't think this court circus is warranted, but neither was Trump's character assassination of Cruz and DeSantis.
No argument from me on the interpersonal concerns you bring up, and I know you are well aware that I am not a Trump fan. But, from the nose holding perspective, I think we are at the "circle the wagon" phase, no matter how big a POS Trump is. We can not survive 4 more years of Pedo Joe.
In any case, my negative comments were just directed towards Bobert and Gaetz
