Most scientists in this country are Democrats.

Slate reports:

It is no secret that the ranks of scientists and engineers in the United States include dismal numbers of Hispanics and African-Americans, but few have remarked about another significantly underrepresented group: Republicans.

No, this is not the punch line of a joke. A Pew Research Center Poll from July 2009 showed that only around 6 percent of U.S. scientists are Republicans; 55 percent are Democrats, 32 percent are independent, and the rest "don't know" their affiliation.

When colleges are subsidized by the federal government : it's no surprise that people who work at universities have a vested interest in more government.
