Professors and other educators donated more than $12 million to political candidates in this last election cycle, with 69 percent of their contributions going to Democratic candidates and PACs, according to the Center for Responsive Politics (CPR).

The overwhelming majority of this giving came from the higher-education sector, judging from the CRP’s top-20 list: Employees at major colleges and universities accounted for 17 of the 20 biggest sources of donations. The University of California system led the way, with contributions totaling $406,000 (87 percent for Democrats), followed by Harvard ($315,000, with 90 percent for Democrats) and the University of Pennsylvania ($196,000, with 94 percent for Democrats).

These patterns in 2006 are nothing new. In 2004, when political giving kicked into overdrive for the presidential race, educators contributed $36.8 million to candidates, with 78 percent going to Democrats.
