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.

We are moving in exactly the wrong direction in higher education. Forty years ago, tuition in some of the great American public universities and colleges was virtually free. Today, the cost is unaffordable for many working class families. Higher education must be a right for all - not just wealthy families.

What I would say to the establishment is that there is far more discontent among the American people than they believe.

97 percent of the scientists who wrote articles in peer-reviewed journals believe that human activity is the fundamental reason we are seeing climate change.

I thought the Bush economic policy was a disaster. We lost 500,000 private sector jobs during his tenure.

Clearly we must do everything we can to protect our country from the serious potential of another terrorist attack, but we can and must do so in a way that also protects the constitutional rights of the American people and maintains our free society. We can do that without living in an Orwellian world where the government and private corporations know every telephone call that we make, every website we visit, everyplace we go.

I prefer to stay on the important issues facing the American people.
