You asked Marco Rubio if it was too little too late. I think there's a little bit of too much too late, which is, he is just getting down in the muck with Donald Trump. And when you get down in the muck, you get up with muck on you.

I think Katrina is one more indication of how inefficient and corrupt this Administration is, and indicates the absolute lack of seriousness that [George W.] Bush has in making the government respond to the needs of the people. They are so separated from the lives of normal, low-income people that it never occurred to them that if you're poor and have no money, no car, that you can't leave.

I think, while it is true that the Hillary Clinton and I voted differently on the war in Iraq, what is important is that we learn the lesson of the war in Iraq. And that lesson is intrinsic to my foreign policy if elected president, is the United States cannot do it alone. We cannot be the policeman of the world. We are now spending more I believe than the next eight countries on defense. We have got to work in strong coalition with the major powers of the world and with those Muslim countries that are prepared to stand up and take on terrorism.

There is a reason why these people [from Wall Street] are putting huge amounts of money into our political system. And in my view, it is undermining American democracy and it is allowing Congress to represent wealthy campaign contributors and not the working families of this country.

Being Jewish and having lost relatives in the Holocaust, I've always been aware of the meaning of prejudice. These are things that have remained with me throughout my political career.

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 believe what I call common sense gun reform. Plus, a revolution in mental health, making sure that if people are having a nervous breakdown, or are suicidal, or homicidal, they get the care they need when they need it. I think the vast majority of the American people can support and agenda composed of those features.
