As a nation, there are many issues we don`t talk about, we just don`t talk about, push them under the rug. Poverty is one of those issues.

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.

Do the elected officials in Washington stand with ordinary Americans - working families, children, the elderly, the poor - or will the extraordinary power of billionaire campaign contributors and Big Money prevail? The American people, by the millions, must send Congress the answer to that question.

Ben Carson and I don`t have much in common politically. But the fact is when you have kids getting involved in the political process, doing their best to elect the candidates of their choice, that`s what the American democracy is about.

Every candidate running for president has got to answer the following very simple question: At a time when we need to address the planetary crisis of climate change, and transform our energy system away from fossil fuels and into energy efficiency and sustainability, should we continue to give $135 billion in tax breaks and subsidies over the next decade to fossil fuel companies?

You know, let me be very clear. I supported Barack Obama originally.
