Rockefeller GOP I solute you in your cause of disproving the democrats propaganda that the majority of republican voters are poor uneducated whites.
True. Also, keep in mind Evangelicals of virtually all education levels (I suppose I'm not sure about PHD's) tend to vote Republican. There are far too many simplifications along the lines of "The GOP is just uneducated rural white rednecks," even though it certainly has a degree of truth to it.
I suspect from experience the Evangelicals who go for PhDs still vote Republican but that there are simply very few of them. From the few I do know, I gather the winds are changing somewhat, but there has definitely been historical disdain for higher education in Evangelical circles. It's almost like a little bit of
William of Occam's views on faith and reason have lived on in Evangelical thought and which discourage the use of reason. Indeed, I wonder if part of academia's liberalism is
because of Evangelicals dislike of it.
