I just read an article
https://www.insidehighered.com/news/2012/10/24/survey-finds-professors-already-liberal-have-moved-further-left written several years ago that reviewed a research project that included the self assessed political viewpoints of professors. It found that about 63% of 4 year university faculty considered themselves Liberal and only 13% considered themselves conservative! The rest were in the middle. Further, the study noted that in 2011 the trend was toward greater liberalization!
We need to inspire more conservative Christians to find their calling in the academic world! Here are a couple professors who did (Robert Maranto and Matthew Woessner) and they are encouraging others to do the same.
