I think you could offer seven or eight different possible ends for energy policy. Climate change is one of them. Dealing with criteria pollutants is one of those related to that.

I came from a state where 35 percent self-identify as Tea Partiers, so I'm a bit distorted perhaps in my appreciation for the larger American population.

But it was very hard for people to separate me out from Hillary Clinton. All their ads were Hillary Clinton, John Kerry, John Edwards, and me. They said I was more liberal than these guys, and that if I went to Washington I'd be supporting their agenda. I found that extremely difficult to overcome.

In the U.S. I think there are really two reasons we should pursue energy policy. One is climate change, and the second is this notion that the oil market is cartel-ized by people, some of whom are friendly, some of whom are not, some of whom are in a more ambivalent position to us.

I mean, the country is deeply divided. There is 35 percent of the people who are Tea Partiers or more in some of those states. So it's probably going to be a difficult year, but there's nothing that I think anyone can do about it.

There aren't that many policy changes you can do, so I'd say you ride the wave and hope that maybe some of the external events help you.
