Today marks a symbolic vote in the Senate: Sen. Jim Inhofe (R-Okla.) is putting forward a Congressional Review Act resolution [PDF] that would stop the EPA’s impending standards on mercury and other toxic power plant emissions in their tracks.

I won’t rehearse all over again why the mercury rule — mandated by court order, more than a decade overdue — is such a big deal, or why further delaying it is a terrible idea, or how it fits into a comprehensive GOP plan to dismantle the system of U.S. environmental law, a plan relentlessly advanced by the most anti-environmental House in the history of Congress. Nor will I go on about how popular it is with the public. UPDATE: As Philip reported, and as expected, Inhofe’s resolution was defeated in the Senate, 53-46.
