If you look back at the 1960's in the United States, and if you think that more good was done than harm, you are probably a Democrat. If you think that more harm was done than good, then you're probably a Republican.

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.

To the extent that our workers compete with low-paid Mexicans, it is as much through undocumented immigration as trade. This pattern threatens low-paid, low-skill U.S. workers. The combination of domestic reforms and NAFTA-related growth in Mexico will keep more Mexicans at home. It is likely that a reduction in immigration will increase the real wages of low-skilled urban and rural workers in the United States.

We've had periods of meanness in American politics. Actually, the dawn of partisan division in America was basically in George Washington's second term, when it was obvious that he would be the first and only consensus president.

That is, we're into a whole new world with the Internet, and whenever we sort of cross another plateau in our development, there are those who seek to take advantage of it. So this is a replay of things that have happened throughout our history.

My fellow Americans, all of us in this grand hall and everybody watching at home, when we vote in this election, we'll be deciding what kind of country we want to live in. If you want a winner-take-all, you're-on-your-own society, you should support the Republican ticket. But if you want a country of shared opportunities and shared responsibility, a we're-all-in-this-together society, you should vote for Barack Obama and Joe Biden.

You know the one thing that's wrong with this country? Everyone gets a chance to have their fair say.
