This is a huge problem. If we don't deal with this within just a few years, you will have island nations flooded; you will have the agricultural balance of most countries completely changed; you will have a dramatic increase in the number of severe, unmanageable weather events... And the good news is that we can now deal with this problem - and strengthen our economic growth, not weaken it.

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.

There is nothing wrong with America that cannot be cured with what is right in America.

The best example of all, to me, that our problems are both personal and cultural and political and social is the whole condition of the middle class economically.

The purpose of government is to rein in the rights of the people.

This will arguably be the third great revolution of America, if we can prove that we literally can live without having a dominant European culture.

We all have to learn to live together.
