Some people call it global warming; some people call it climate change. What is the difference?

The fundamental problem for Republicans when it comes to the environment is that whatever you say is viewed through the prism of suspicion.

I would not have used the phrase "I'm selling you" because even though that's exactly what you're doing, when you tell people you're doing it - or worse yet, when you tell people "I'm not here to sell you anything," they automatically assume that that's exactly what you are here to do.

The Tucson speech [of Barack Obama] was brilliant, and I'm so angry at Republicans for jumping on him because you have to give credit. Part of being successful is to give credit to people who you may not disagree with when they do well.

I had nothing to do with death panels. I thought it was a horrible phrase about end of life. I didn't think it was accurate, and I was - I've always been opposed to it. The reason why I stood behind that phrase "death tax" for so many years is because the only time that you could pay that tax, the only time, is on the death of a relative. And that's what makes it a death tax. You have to be accurate.

You need good principles and good language if you are to succeed.

We are so divided, and we recognize that we're divided, that we're looking for ways to come together.
