Yeah, I'm seeing the science bloggers/Youtubers I follow (Phil Plait (Bad Astromony), Emily Lakdawalla of the Planetary Society, Diana Cowan (Physics Girl)) being much more political these days and that's one of the things they are saying. In some ways, I wish they would take it on. All three are excellent communicators so they could easily run or help someone else run. I think science educators like them would actually make better candidates than scientists proper, who tend to be a bit out of touch with things outside their own research field. Science promoters/educators are used to distilling science for the masses (ie. for voters) and being advocates for science and scientific concepts to the general public. I guess Bill Nye (Emily's boss, by the way, since he's the current CEO of the society) would be the obvious option for a high profile science candidate to run for some public office or other. He has some political liabilities, though, esp. in parts of the country where the religious right (ie. creationists) are strong.
Nye? As Lutheran Humor has pointed out in one of their videos, he has a Bachelors degree in mechanical engineering and he used to pretend to be a scientist on television.
