The Secular Vote in 2024 (Part One)

Apr 25, 2025 4:07 pm

Last week, I attended the American Atheists Convention in Minneapolis. Aside from meeting new friends, finally meeting some online friends in person, and catching up with old friends, I had the chance to discuss some of the material I have previously published in this newsletter.. I finished my presentation with some notes for future posts. These future posts will focus on the 2024 election, primarily because several data sources related to the 2024 elections have become available in the last few weeks. Today, I will focus on the VoteCast survey conducted by the Associated Press and the National Opinion Research Center.


 The VoteCast survey finds that the most likely group to vote for Kamala Harris in 2024 was the secular cohort. According to the study, 68%, or more than two-thirds, of secular voters cast their ballots for Kamala Harris. About three-in-ten (29%) voted for Donald Trump. Among religion groups that voted a majority for Kamala Harris, the secular cohort is by far the largest. This aligns with my previous post following the election, which found that the Exit Polls suggested the secular cohort was the only one that didn't budge significantly in terms of its support for the Democratic presidential candidate.

As shown in the chart, approximately two-thirds of secular voters and Jewish voters supported Kamala Harris. That is in line with their historical pattern, especially in this century. About six-in-ten Muslim voters and voters who belong to other religions also voted for Harris. By contrast, majorities of groups identified as Christians voted for Donald Trump in 2024. The lowest proportion was 54% of Catholics, increasing to 64% among Mormons. Among white Evangelical Christians, 76% voted for Trump (not shown). This is higher than any other group, but the survey's measurement of “born again/evangelical” is confusing, so I excluded it from the chart.
