Turning 50 gives me more yesterdays than tomorrows.

[George Bush] has raised taxes on the people driving pickup trucks and lowered taxes on the people riding in limousines. We can do better.

The Kyoto Treaty wasn't perfect, but we signed it, in fact, helped to draft it. And I'm very proud of it, it was the world's first commitment to doing something comprehensive on greenhouse gases and trying to reduce global warming before we do irreversible damage to many civilizations around the world.

My father left me with the feeling that I had to live for two people, and that if I did it well enough, somehow I could make up for the life he should have had. And his memory infused me, at a younger age than most, with a sense of my own mortality. The knowledge that I, too, could die young drove me both to try to drain the most out of every moment of life and to get on with the next big challenge. Even when I wasn't sure where I was going, I was always in a hurry.

America just works better when more people have a chance to live their dreams.

The power of our example is more important than the strength of our military.

Every time Bush talks about trust it makes chills run up and down my spine. The way he has trampled on the truth is a travesty of the American political system.
