The whole idea that people who vote for one party rather than another one can lay claim to be more intelligent is as ridiculous as claiming to be a better athlete because he or she rooted for a popular football team.
Matter of fact science students, engineers etc have little time for politics and/or political activities. It`s the rest of the "academic" crowd, of the non scientific disciplines, with an easier curriculum that have a lot of spare time to engage in political activities, are liberal and bully everyone who does not agree with them. A few weeks ago I watched a program called "brain games" with my kids on the National Geographic channel.

On that episode a group of students were given the task to draw a bicycle.
They never did say which university it was, but with the exception of one the rest of them were not able to draw a bicycle that would have been functional. So were they all "Tea party" or Republicans ?
I bet every one of them had chanted with Obama "yes we can". Maybe not the guy who was able to sketch a bicycle that would have worked.
In another test how a zipper works the outcome was the same sorry result.
