The good news is that we've seen in recent years significant reductions in the cost of solar panels and wind production. We know how significant an impact we can have by moving towards energy efficiency and transforming our transportation system. So we know what has to be done. We have to develop the political will to do it, and, as president, this would be an issue of huge concern to me.

Let us wage a moral and political war against the gross wealth and income inequality... ...let us understand that when we stand together, we will always win.

But because media is what media is today, any stupid, absurd remark made by Donald Trump becomes the story of the week. Maybe, just maybe, we might want to have a serious discussion about the serious issues facing America. Donald Trump will not look quite so interesting in that context.

To my mind, if we do not get a handle on money in politics and the degree to which big money controls the political process in this country, nobody is going to bring about the changes that is needed in this country for the middle class and working families.

The United States has more people living in poverty than at almost any time in the modern history of our country. I believe that in a democratic, civilized society none of our people should be hungry or living in desperation. We need to expand Social Security, not cut it. We need to increase funding for nutrition programs, not cut them.

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.

We need to recognize the incredible challenges that so many parents face, especially working moms. We need to join the rest of the advanced world.
