Low-income people, racial or ethnic minorities, pregnant women, seniors, people with special needs, people in rural areas - they all have a much harder time accessing a dentist than other groups of Americans.

For Democrats to win, they're going to have to address the needs of working people. They're going to have to address the needs of the middle class. And that means standing up to Wall Street, standing up to the greed of corporate America. Even now and then, standing up to the media. And that means having a candidate who can excite working families, excite young people, bring them into the political process, create a large voter turnout.

I don't believe in trashing my opponents. I've never run a negative ad in my life. I believe in talking about issues, sometimes fighting for the media to talk about the issues, but that's what I do, and the people will decide.

I have introduced a constitutional amendment to overturn Citizens United and make it clear that the Congress and state legislatures do have the ability and the power to regulate and get corporate funding out of political campaigns.

In terms of media, we did not get the kind of media attention that somebody like a Donald Trump got, because media is not necessarily interested in the issues facing the middle class, more interested in attacks in personality. So I think there were a lot of reasons.

20 million people thrown off of health insurance, prescription drug prices raising for seniors, privatization of Medicare: devastation. And we've got to fight back against that.
