In 1951, William F. Buckley declared the university to be a den of atheism and anti-capitalism in his book “God and Man at Yale,” launching a campaign against higher education that has helped define postwar conservatism. Judging from today’s political landscape, not much has changed. On the campaign trail, Marco Rubio called the university an “indoctrination camp,” while Ben Carson promised to deny federal funding to schools that show sharp political biases.
