The science-based community once was split between Democrats and Republicans -- but not anymore.
The expertise gap itself is becoming dramatic. In one of the most comprehensive surveys of American professors, sociologists Neil Gross of the University of British Columbia and Solon Simmons of George Mason found that 51 percent described themselves as Democrats, and 35.3 percent described themselves as independents--with the bulk of those independents distinctly Democrat-leaning, rather than straddling the center.
Just 13.7 percent were Republicans. Academia has long been a liberal bastion, but it hasn't always been this lopsided. According to Gross, professors have been drifting to the left since the late 1960s, gradually carrying us into today's very unbalanced expertise environment.
Gross and Simmons' findings parallel the results of surveys on two overlapping groups: scientists and those with graduate degrees (whether or not they stay in academe). A 2009 survey of
American Association for the Advancement of Science members found they were overwhelmingly more Democratic, and more likely to describe themselves as liberal, than the general public. Fifty-five percent were Democrats, 32 percent were independents, and just 6 percent were Republicans. Then there are all the folks with letters after their names. Ruy Teixeira of the Center for American Progress has shown that Americans with a post-graduate level of education have been trending more and more strongly Democratic in the past three presidential cycles. They supported Al Gore by a margin of 52 percent to 44 percent in 2000, John Kerry by 55 percent to 44 percent in 2004, and Barack Obama by 58 percent to 40 percent in 2008.
