"A lot" is an understatement. He can never recover. I expect him to serve some jail time in a few years. Probably as a result of the NY tax cases.
Beyond him, MAGA is dead, America First is dead, the 2A is dead, and the R party is dead. Romney may emerge as the head going forward as it tries to save itself, with maybe Tom Cotton the alternative.
R votes for amnesty will signal the shift. MAGAers will recoil and stop donating, participating. Party will further move away to survive, etc, resulting in a spiral to irrelevance on the national stage. And quickly. MAGAers were the ground force of volunteerism.
I don't see even De Santis offering a life raft anymore. Cruz and Hawley will lose their re-elections in 2024 to seal the movement's fate.
