Their study finds a correlation between white American’s intolerance, and support for authoritarian rule. In other words, when intolerant white people fear democracy may benefit marginalized people, they abandon their commitment to democracy.
…Based on surveys from the United States, the authors found that white people who did not want to have immigrants or people of different races living next door to them were more likely to be supportive of authoritarianism. For instance, people who said they did not want to live next door to immigrants or to people of another race were more supportive of the idea of military rule, or of a strongman-type leader who could ignore legislatures and election results.
…In practice, the GOP has increasingly been embracing a politics of white resentment tied to disenfranchisement. “Since Richard Nixon’s ‘Southern Strategy,’ the GOP has pigeon-holed itself as, in large part, an aggrieved white people’s party,” Miller told me.
Trump’s nativist language made the GOP’s sympathies more explicit, leading to further erosion of support among non-white voters.
…The GOP, seeing their coming demographic apocalypse, has pushed voter ID laws and other barriers to voting to try to prevent black and other minority voters from getting to the polls. In Wisconsin, Republican Governor Scott Walker even attempted to delay elections for state seats that he believed Democrats would win.
…”Social intolerance isn’t just leading to GOP support as we know it and see it now,” Miller says. “It’s leading to preferences in favor of the kind of candidate the GOP ultimately nominated and supported for president.” In embracing the politics of white identity, then, the GOP made a Trump possible — and is likely to make more Trump-like candidates successful in the future.
