In this article I offer new evidence about something readers of Academic Questions already know: The political registration of full-time, Ph.D.-holding professors in top-tier liberal arts colleges is overwhelmingly Democratic. Indeed, faculty political affiliations at 39 percent of the colleges in my sample are Republican free — having zero Republicans. The political registration in most of the remaining 61 percent, with a few important exceptions, is slightly more than zero percent but nevertheless absurdly skewed against Republican affiliation and in favor of Democratic affiliation. Thus, 78.2 percent of the academic departments in my sample have either zero Republicans, or so few as to make no difference.
My sample of 8,688 tenure track, Ph.D.–holding professors from fifty-one of the sixty-six top ranked liberal arts colleges in the U.S. News 2017 report consists of 5,197, or 59.8 percent, who are registered either Republican or Democrat. The mean Democratic-to-Republican ratio (D:R) across the sample is 10.4:1, but because of an anomaly in the definition of what constitutes a liberal arts college in the U.S. News survey, I include two military colleges, West Point and Annapolis.1 If these are excluded, the D:R ratio is a whopping 12.7:1.
In this paper I find that D:R ratios among fifty-one of the top sixty-six U.S. News-ranked colleges average 10.4:1., Excluding Annapolis and West Point raises the ratio to 12.7:1. This compares with a national D:R ratio of 1.6:1 for people who have some graduate school experience.
Some STEM fields come close to the baseline national average of 1.6:1; potentially ideologically linked fields, especially the interdisciplinary studies fields, do not. Thus, the D:R ratio for engineering is 1.6:1 while for the interdisciplinary studies fields it is 108:0.
Institutional factors at the state government level as well as at the individual college level may play some causal role. Professors in more Democratic states, especially in New York and New England, are more often affiliated with the Democratic Party than in other states.
Since the 1960s, a few liberal arts colleges have not conformed to the homogenizing trend, and these demonstrate that institutional characteristics, at a minimum, contribute to faculty political affiliation in liberal arts colleges. Thomas Aquinas is all Republican, and the two military colleges in my sample, West Point and Annapolis, have D:R ratios of 1.3:1 and 2.3:1. Studies that focus on grand means ignore the association of affiliation rates with institutional characteristics.
