Trump Derangement Index

A one‑number measure for an individual that reports how strongly they would prefer any available alternative to Donald Trump on a 0–100 scale (0 = prefer Trump to anyone; 100 = would prefer the most anti‑Trump candidate, e.g., Mamdani, to Trump). It converts affective polarization into a simple comparative preference metric that can be asked in polls or appended to existing surveys. — Making tribal antipathy quantitatively legible would let pollsters, researchers, and media distinguish principled cross‑ideological preferences from reflexive anti‑Trump status signaling and track how elite endorsements move mass affect over time.
