4th category, D: Democrat haters.

is this a small group?
mostly rational in all discussions, yet they simply cannot imagine that a trump threat is worse than proven Dem outperformance.

look no further than this week's PBS interview with former ambassador to russia for ~1 year under both trump and biden.
although far more critical of trump PER HIS OWN experience doing a difficult job as a public servant, he finishes the interview saying he will vote for trump, thus becoming effectively as clueless as any of the more MAGA groups.

in book & interview:
"Trump had a undisciplined style, The White House was chaotic, unpredictable, the president could not or would not draw a distinction between his own interests and those of the country, Trump has no interest in the ordinary duties of his office."
