WaPo's Sebastian Mallaby abases himself trying to find some argument for why President Bush is now a leader on climate change and carbon emissions.

On Saturday I put the case for a carbon tax or a cap-and-trade system to James Connaughton, the head of the Council on Environmental Quality at the White House. Far from denouncing these policies as eco-socialist nonsense, Connaughton sounded open to them. "In concept I can agree with you," he said. Something must be done to stem demand for climate-warming energy, and although there are several ways of getting there, a carbon tax or cap-and-trade system would be the most "elegant."

Whoa! This may be spin, but it's certainly new spin. Only a few months ago, Al Hubbard, director of Bush's National Economic Council, brushed aside the idea of a carbon tax: "The American people are not interested in paying more for gasoline," he told me, sounding like a frog in the path of a herd of elephants who says he's not interested in jumping.
