I agree. I went through engineering, and I had no problems with any of my ChemE or EE professors. They were professional, and appeared apolitical in class. My guess is that many were conservative/Republican.
Frankly, it has become an embarrassment to be a part of higher Ed. I retire in about 2 months and will be glad to get away from what was once an enjoyable pursuit of hard science, teaching professional students, and veterinary services.
