I think that unlike some others in the maga leadership, she was a true believer. She believed in all the most dubious deep state conspiracy theories. She thought this movement was about purging deep state corruption, and replacing it with some more meritocratic system. A big old dose of racism in there but with her rationalizing it with convenient conspiracy theories.

Now she’s faced with more blatant objective evidence of conspiracies. So she gets turned a bit by the betrayal.

Over a long enough time span, I think MTG is doomed to always, eventually turn against whomever is ostensibly “in charge”. She’ll go for conspiracy theories and of course the people in charge are to blame.
