From http://verdantlabs.com/politics_of_professions/
Source of data: Campaign contribution data from the FEC.
First image, college professors, for comparison. Second image, occupation titles in religion.
College professors lean heavily Democratic regardless of field. In religion, the range is much wider. Missionaries and Catholic priests lean heavily Republican. Rabbis and Episcopal Priests lean heavily Democratic.
For religion: Missionaries most Republican, Episcopal priests most Democratic measured by campaign donations. pic.twitter.com/Q5aPSkCTnS
