", "\n\nObjectives\nSupport for Donald has been linked to religious commitments and education, though the issue of how cognitive sophistication may play a role in his support has rarely been examined. This study explores how cognitive sophistication and religion influenced political orientations and Trump voting.\n\n\nMethods\nData from the 2018 General Social Survey are examined. Logistic regression is used to predict voting and choice. Structural equation models are estimated to examine the interrelationships between cognitive ability, education, religious commitments, political orientations, and the Trump vote.\n\n\nResults\nCognitive sophistication was found to have a positive effect on voting, but a negative effect on choosing Trump. The influence of cognitive sophistication works through its support for secular beliefs and opposition to biblical inerrancy, influencing Republican partisanship and political conservatism that favored Trump.\n\n\nConclusions\nCognitive sophistication and educational attainment are important for influencing political commitments and the Trump vote, and the effect of cognitive sophistication is entwined with its negative association with religious fundamentalism and positive association with secularism.\n\n"]
