We added Medicare Part D to a system facing bankruptcy and gave no thought to means testing it.

I represented the 4th District of South Carolina... from the election '92 until election '98. And then I was out six years and then came back for another six years between the election 2004 and the election 2010.

There's a lot of Republicans who may have in the past been critical of fellow Catholics who they call 'cafeteria Catholics' who don't follow the church's teachings - say, on abortion. But now, are they going to become 'cafeteria Catholics' themselves and not follow the church's teachings on climate change?

Many conservatives, I think, see action on climate change as really an attack on a way of life. That`s really a hard pill to swallow, that the whole way that I have created my life is wrong, you`re saying, that I shouldn`t have this house in the suburb, I shouldn`t be driving this car.

So when you're dealing with an existential threat like death or like climate change, if you see it as 'we are all toast anyway,' then denial is a pretty good way of coping.

I think we`re all experiencing climate change. Experience is an effective teacher. It`s sometimes a very harsh teacher. So we will be taught about climate change.

Our hope is we move beyond denial and into debate... If we cleaned up the air, would it really be bad for us?
