The Natural Resources Defense Council (NRDC) is a giant among anti-science groups, a $100 million per year juggernaut that is able to bully companies into writing checks in return for calling off the invective among the many satellite organizations in its orbit.
Republicans in the Senate seem to have finally had enough.
At issue is a series of political ads targeting Sen. Mark Kirk (R-Ill.), who is considered vulnerable by NRDC and other anti-science organizations. They would like him replaced with someone more reliable - in this case Rep. Tammy Duckworth (D-Ill.). The NRDC insists it is just informing voters and that its ads against Kirk are public education, not political advocacy.
Obviously the line between education and politics is fuzzy and NRDC has long been able to control their public perception with a well-funded advertising machine: Those full-page ads in the New York Times can't hurt when it comes to getting positive coverage from journalists - and having media ignore their ethical warts.
