Yeah, MAGA is just an expression of the things set in motion by the Powell Memo (in some ways Trump hijacked that infrastructure for his own profit instead of sharing amongst the other sponsors of that plot). All those conservatives in the courts and in safe red districts will just stay where they are and spin up some new 'movement' like the Tea Party before it.
Conservatives can easily be convinced to believe the opposite of what they believed just a few years ago, look at how they turned in George W Bush basically effortlessly.
I know these particular charges are probably bullshit, but I don't think there should be a statute of limitations for lying to Congress.
