Things will have to be really really bad for MAGA to notice and then actually acknowledge issues. Even then they might use excuses and blame others.
COVID handling was objectively terrible, with plenty of examples of mismanagement, but they’ve basically completely forgotten about it and the ‘mismanagement’ they might point to are the availability of vaccines, or the ability of workplaces to make people wear masks.
They can also completely ignore the blatant corruption with employing close family members as advisors and diplomats, while on the other side, even leaning on a family name to get a job was too much. Don’t forget that they’ve also come to the conclusion than Jan 6 wasn’t bad.
An unusual counterpoint. The ‘krompomat’ the Russians wasn’t really proven, and at this stage I think if they threaten him with releasing whatever Trump can just go ‘LOL like I give a fuck. You seen the shit I did to their face? They still voted for me!’
