The polarization of hurricane opinion?

A difference-in-differences analysis demonstrates that Trump/Clinton vote share strongly predicts evacuation rates, but only after the emergence of conservative-media dismissals of hurricane warnings in September 2017, just before Irma made landfall in Florida. Following this viral “hurricane trutherism”, we estimate that Trump-voting Florida residents were 10-11% less likely to evacuate Irma than Clinton-voters (34% vs. 45%) after controlling for key demographic and
geographic covariates, highlighting one consequence of political polarization.
