What we're trying to do is address something I saw in Congress that was a major problem, which is to say that energy is arguably the most fundamental issue confronting our country.

There are philosophical issues involved in that about choosing the right discount rate, the value, the future, and things like that which drive it. But its start with the premise that global warming is real and if you're a denier of that fact, then you're not going to find climate change mitigation policies to have particular appeal.

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.

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.

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.

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.
