If elected president I will have a litmus test in terms of my nominee to be a Supreme Court justice. And the nominee will say, we are going to overturn this disastrous decision on Citizens United because that decision is undermining American democracy. I do not believe that billionaires should be allowed to buy politicians.

If Mr. Trump wants to work with us to make sure that trade works for the American worker, not just CEOs of corporate America, you have got a partner, partner.

For many, the American Dream has become a nightmare.

When a mother has a baby, she should stay home with that baby.

We're not going to give tax breaks to billionaires and then cut back on the needs of our elderly or poor or kids or education. We're not going to privatize Social Security - in fact, we're going to strengthen it. We're going to provide quality education for every kid in America, from preschool through college. We have to take on these corporate leaders who are selling out the American people, whose allegiance is now much more to China than it is to the United States. If we have the courage to take these people on, I think we can overwhelm George W. Bush and his friends.

I think it makes people in the Pentagon kind of nervous to know that chemical agents and environmental factors could cause so much damage in terms of what may happen in the future.

Trickle down economics is a fraud. Giving tax breaks to the rich and large corporations does not create jobs. It simply makes the rich richer, enlarges the deficit and increases income and wealth inequality. We need economic policies which benefit working families, not the billionaire class.
