Why only 6% of the scientists are Republican, 55% Democrat, and ...

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.
This immense imbalance has political consequences. When President Obama appears Wednesday on Discovery Channel's Mythbusters (9 p.m. ET), he will be there not just to encourage youngsters to do their science homework but also to reinforce the idea that Democrats are the party of science and rationality. And why not? Most scientists are already on his side

It turns out that not many scientists are Republicans. Just 6%.

A full 87 percent of American scientists see their political alignment as Democrat or Independent, according to a new Pew Research poll.

Surprisingly or not, just six percent declared themselves Republican, and only nine percent overall expressed support of conservative ideology.

Most scientists identify as Democrats (55%), while 32% identify as independents and just 6% say they are Republicans.
