Today’s election watch features “A Vote For Science”, a campaign to get scientists to video themselves explaining who they will be voting for.

So far only one video is available on their YouTube site, but it’s a big fish: new Nobel Laureate Martin Chalfie (as featured in a Nature interview published yesterday).

Chalfie has previously announced that he will be backing Barack Obama. In his new video he says:

I’m a scientist and I am voting for Barack Obama.

Hear why in the video.
