I take full responsability...for what we did. It was the right thing to do.

Some day we hope to liberate every man on earth from the tendency as old as human history to identify our strength and manhood with the ability to control the lives, limit the chances, and doom the dreams of women and girls.

I think the Democrats are going to have to be willing to give up, maybe, some short-term political gain by whipping up fears on some of these things - if it's a reasonable Social Security proposal, a reasonable Medicare proposal. We've got to deal with these things. You cannot have health care devour the economy.

We have a unique opportunity to unite America, urban and rural, coastal and midwestern, red and blue, under the banner of a truly unifying national effort. We can start right now.

The divide of race has been America's constant curse. Each new wave of immigrants gives new targets to old prejudices. Prejudice and contempt, cloaked in the pretense of religious or political conviction, are no different. They have nearly destroyed us in the past. They plague us still. They fuel the fanaticism of terror. They torment the lives of millions in fractured nations around the world. These obsessions cripple both those who are hated and, of course, those who hate, robbing both of what they might become.
