Alaska Sen. Lisa Murkowski said Wednesday that opening the Arctic National Wildlife Refuge to oil drilling might be the price of her swing vote in favor of energy and climate legislation. But The Hill reports today that Sen. Joe Lieberman -- a longtime opponent of ANWR drilling -- says ANWR drilling would be a "deal breaker" in his attempt to craft a bipartisan climate bill.

"That is just not going to happen," he told reporters in the Capitol.

Lieberman - who has long championed efforts to keep ANWR permanently off-limits to drilling - is trying to craft a compromise climate and energy plan with Sens. John Kerry (D-Mass.) and Lindsey Graham (R-S.C.).

"We are looking at a lot of things, we are bending to bring people in, but that one is a no-no," he said.

Meanwhile, The Hill reports today that Murkowski is supporting Sen. Jay Rockefeller's (D-W.Va.) bill to block EPA regulation of greenhouse gas emissions from industrial facilities for two years - even though she has a broader bill pending.

Murkowski - who has 40 co-sponsors for her competing plan ... said she's keeping her own plan at the ready if it doesn't advance.
