Could Massachusetts Sen.-elect (and sound climate science advocate) Scott Brown be wrecking the Democrat agenda across the board? Alaska Sen. Lisa Murkowski was joined today by three Democrat colleagues — Arkansas’s Blanche Lincoln, Louisiana’s Mary Landrieu, and Nebraska’s Ben Nelson — in a move to prevent EPA from regulating greenhouse gas emissions. From the Guardian:

Murkowski’s move, brought under the Congressional Review Act, would remove the Obama administration‘s “Plan B” for dealing with climate change, resorting to the EPA to curb greenhouse gas emissions if Congress fails to act.

The motion of disapproval, called the “nuclear option” by environmentalists, would also ban the administration from drafting any new regulation that would be substantially the same. That would make it even more difficult for any US government to regulate power plants and other big emitters.

Environmentalists say the proposal is unlikely to pass, but ensuring its defeat could require a new round of partisan warfare that could be damaging for Democrats and Obama’s agenda.

Why, oh why, would these three Dems do such a thing? Politico sez:

Lincoln, a politically vulnerable senator who comes from a manufacturing state that leans Republican, warned that “heavy-handed EPA regulation, as well as the current cap and trade bills in Congress, will cost us jobs and put us at an even greater competitive disadvantage to China, India and others.”

Sen. Mary Landrieu (D-La.) is also working with Murkowski on proposals to stop the EPA from regulating greenhouse gases under the Clean Air Act.

The Democrats are bucking Majority Leader Harry Reid (D-Nev.), who has criticized the Murkowski proposal.

Amazing the new pals the GOP is making, and the greens are apoplectic…
