It's complicated. Certainly there are some with low intelligence who are easy to manipulate. Others have been radicalized by extreme, repetitive, right-wing propaganda. Many are fearful and angry due to changing cultural norms and demographics and pine for a strong authoritarian leader to save their way of life. Some feel ignored and looked down upon so they are highly receptive to demagoguery.  With others their self-identify is all wrapped up with MAGA and makes them intractable and consequently overly protective, defensive, and combative toward critics and legitimate media. Someday, when this malicious movement is gone, historians and authors will chronicle copious volumes of this dark period in our history replete with cautionary tales. Future generations will ask "what the fuck were they thinking?".

The best response would have been "I don't know, you seem to be coping very well with it why don't you give us some pointers?"
