There hardly exist any, reports Daniel Sarewitz. Only 6 % of scientists self-identify as Republican. There is probably a bigger percentage of blacks in the Ku Klux Klan than that. He wonders why, but Kevin Drum isn't so puzzled:
Of course scientists are hostile toward Republicans. As far as they're concerned, Republicans are troglodytes who don't believe in evolution, don't believe in climate change, want to ban stem cell research, and don't want to fund the NSF. They'd be crazy not to be hostile toward Republicans.
My guess is that relatively few scientists are ideologues of right or left, and that there would be, will be, more Republican scientists as soon as Republicans stop being no nothing dumb shits ... like than's going to happen anytime soon.
