Second, you will tend to find differences among different departments. There are probably more Dems and liberals (whatever that means) in the humanities and social sciences, relatively more GOP and conservatives (whatever that means) in the natural sciences, business, criminal justice, perhaps medicine.
As a natural scientist that would like to keep teaching evolution I think we would fall into the more liberal side of things. I estimate my department is 60-80% liberal.
I think it is pretty sad that, in the US, one needs to connect "anti-evolution" and "conservatism." (Or evolution and liberalism). In every other country, being anti-evolution reveals you as a wacko.
