Voters with post graduate education are strong supporters of Obama? The more college education people have, the more liberal they tend to be.
Of course there are exceptions. But I bet almost everyone getting a graduate degree in Gay/Lesbian Studies, or Women’s Studies, or various other sociological fields, support Obama, because they are getting advanced degrees due to wanting to push a liberal social/political agenda. People in the hard sciences aren’t always so knee-jerk liberal.
But we can’t talk too much about the hard sciences, and reasons why relatively few women are in those fields. If you raise the questions, feminists will throw up and agitate so much, that a liberal president of Harvard can be fired for that academic inquiry.
