Duncan Currie has a good piece over on the homepage on the EPA’s power-grab:

With oil still gushing into the Gulf of Mexico and partisan recriminations flying on Capitol Hill, the Senate today will vote on a measure to prevent the Environmental Protection Agency (EPA) from regulating greenhouse-gas (GHG) emissions under the Clean Air Act. The resolution, introduced by Alaska Republican Lisa Murkowski, has garnered 40 other co-sponsors, including Democrats Mary Landrieu (La.), Blanche Lincoln (Ark.), and Ben Nelson (Neb.). The only GOP senators who have not signed on are the three New Englanders — Scott Brown (Mass.), Susan Collins (Maine), and Olympia Snowe (Maine) — though Republicans are confident that one or more of them will vote for final passage. West Virginia Democrat Jay Rockefeller, whose home state generates nearly all its electricity from coal, has previously suggested an alternative to the Murkowski proposal that would block the EPA from regulating GHG emissions produced by stationary sources for two years. Earlier this week, however, Rockefeller announced that he would support the resolution championed by his Alaska colleague. “I have long maintained that the Congress — not the unelected EPA — must decide major economic and energy policy,” he said in a statement. “EPA regulation will have an enormous impact on the economic security of West Virginia and our energy future. I intend to vote for Senator Murkowski’s Resolution of Disapproval because I believe we must send a strong message that the fate of West Virginia’s economy, our manufacturing industries, and our workers should not be solely in the hands of EPA.”
