I just want to know why Trump is doing this now cause I don't see how this benefits him.
I believe that Trump has become unhinged. The results of the candidates that he supported didn't turn out all that well and he is being criticized. Meanwhile DeSantis won BIGLY and he sees him as a threat. Why he's starting to go after others only proves that he cannot control his narcissism and chaotic personality.
IMHO he continues this crappola and he will lose support very quickly. He needs to continues to spread the MAGA message and get ready to pass the torch on to someone else. DeSantis, Neom, etc.
Trump was a great president and he should absolutely get a pat on the back. But obviously his knee jerk reactions to the mid terms is indicative that it is time to move on.
