I'm horrible about promotion, and this is long overdue. 
A few weeks ago Scientists and Engineers for America launched the Science Health And Related Policies (SHARP) Network, a nonprofit, nonpartisan, community-driven site that shows how elected officials and candidates stand on important scientific issues.
