“In 1992, those whites scoring at the top of the authoritarianism scale split their two-party vote almost evenly between Bush and Clinton (51 to 49). In 2000 and 2004, the difference becomes statistically significant but still pretty small.
By 2012, those high-authoritarianism white voters went 68 to 32 for Romney over Obama. In both Trump elections it was 80 to 20 among those voters.
So from 50 Republican-50 Democrat to 80 Republican-20 Democrat in 24 years.“
