From one:

Jonah
I am an environmental engineer who has been teaching at the university level
for about 27 years. In that time, I have seen young engineers getting more
and more liberal. What is the reason? Certainly not the five that Delong
lists in his article. I doubt that ANY engineer older than about 35 would
give any of the 5 reasons he lists for being a Democrat. The reason is that
even engineers have to go through the liberal arts to get a degree. It is
hard even for a practical, level-headed person to resist the constant
propaganda that our students are subjected to. The English, history, and
political science professors at my University and elsewhere have cleverly
learned to deconstruct science and plant doubt in the minds of budding
engineers and scientists. I am appalled at the gullibility of these young
professionals. These people believe in global warming with a religious
intensity and will not trust science to prove or disprove it. It is not a
good sign for the future of our country.
