In 30 years of public service, I have had no scandals. I have high ethical standards. I am most proud of my judgement, that kind of judgement is what we want in a president going forward. I want to be a peacemaker.

The billionaires and their super PACs increasingly control the American political process. This is not democracy. This is not what brave Americans fought and died to defend. This is oligarchy. This is government of the few, by the few and for the few. We must overturn Citizen United and move to public funding of elections.

I am not a great fan of the payroll tax holiday because I'm nervous about what it does to the future of Social Security.

The American people understand that we need real change in this country, in my view, a political revolution, which says to the people on top, "You know what, you guys can't have it all."

I understood that these trade agreements were going to destroy the middle class of this country. I led the fight against us. That is one of the major differences that we have.

For many, the American Dream has become a nightmare.

The point is change can come about, but it only comes about when millions of people are actively involved in political struggle, the billionaires may have the money, but we have the people.
