You really think that if trump walked away the republican party would go back to normal. DeSantis is the same or worse than trump.
This is not going away too soon. I know because I have a relative who's all in MAGA. For the last 15-20 years she's complained about being screwed over and wanting a revolution. trump validated her thoughts and now those thoughts are stronger and will never go away (until death). As long as republicans keep feeding her a candidate for her to latch on to, she will continue to be a "MAGA" even if trump isn't around. She will never change her mind at this point for the rest of her life. The problem is, there's about 30% of the people just like her (along with the republican politicians).
