Sen. Lindsey Graham may be under fire from conservatives back home in South Carolina. But the Republican got a personal assurance from President Obama yesterday that the White House is supporting his efforts to craft a sweeping Senate energy and global warming bill. "The president told me personally he was very open, that nuclear power would be part of the mix, that clean coal would be part of the mix, that he's for offshore drilling in a responsible way," Graham said today in describing his Oval Office meeting with Obama. "But we have to have a price on carbon, an emissions standard that's real, that's good for the environment and good for business. And I was very pleased."
