I remember reading a story about the educators at the Univ of Colorado, Boulder, back in the late 80’s. ‘They’ surveyed 198 Profs and 196 declared themselves Democrat. The other two Republican. But after the survey was published, one of the ‘Republicans’ came out as a Democrat saying ‘I was just joking’. The indoctrination has been relentless since I was in college, back in the 70’s. I guess we are fortunate that we have had any Republicans in higher office, in the last 50 years.
When the 60s leftists all graduated college they took over the colleges.
