I read the same report. I basically break down MAGA voters into three groups.
The one you mention are the cultists - they are fundamentally uncritical, politically unaware individuals who blindly follow their saint.
The second are the single issue - voters, the are very narrowly educated on one political interest, and will vote for that, not matter how badly Trump’s other policies affect them or their families.
The last are the slaves to Fox’s (or Breibart, what have you) propaganda. They’re in such an information silo that they never know what is going on, and when challenged, they completely shut down. They don’t want to make their own decisions, they’re comfortable being lead and letting someone else take responsibility.
If I was talking about Republicans, well, there are other versions and flavors, and often some blatant cynicism and grift involved. But I’m not going to pretend that Republicans are now the minority that is almost completely subservient to MAGA.
And, back to the OP, it’s the rest of America that’s getting sucked into an every more tenuous international standing, leading us to:
And they’re not even wrong.
