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

I do believe that in the future, not by dismantling what we have here - I helped write that bill - but by moving forward, rallying the American people, I do believe we should have health care for all.

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.

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.

The truth is that political consciousness in this country is pretty low... To the degree that we can help educate and organize people around the most important issues facing their lives and show that there is support for fundamental changes in the way we do business in the United States of America in terms of income inequality, in terms of low wages, in terms of disastrous trade policies, in terms of being the only major country not to have a national healthcare program - that's success.

I'm a United States senator, and I have a responsibility to the people of my state - also to the people of this country.

We need to change the power structure in America, we need to end the political oligarchy.
