He was for it before he was against it:

“Realistically, the cap-and-trade bills in the House and the Senate are going nowhere,” said Senator Lindsey Graham, Republican of South Carolina, who is trying to fashion a bipartisan package of climate and energy measures. “They’re not business-friendly enough, and they don’t lead to meaningful energy independence.”

Mr. Graham said the public was demanding that any energy legislation from Washington focus on creating jobs, whether by drilling for offshore oil or building wind turbines.

“What is dead is some massive cap-and-trade system that regulates carbon in a fashion that drives up energy costs,” he said.

Mr. Graham’s opinion matters because he has been the only Republican willing to work with Democratic senators on some form of climate change legislation. He said that the price of attracting Republican and business support was to use the legislation to provide incentives for building nuclear power plants, stepped-up domestic oil and gas exploration and subsidies for reducing carbon dioxide emissions from coal.
