I'm not going to tell you I know George W. Bush intimately. I'm not going to tell you we're best friends. I'll tell you I met him on a number of occasions. You know what? George W. Bush is a very nice guy. Very funny guy. His wife is a very nice woman; I thought she was a great first lady. George [W.] Bush was the worst president in the history of the United States of America... The issue is not Bernie Sanders. The issue is the Koch brothers. The issue is who owns America.

The case to be made is that we have got to get people involved - continue to get people involved in the political process at every level.

The American people are growing extremely unhappy with establishment politics, with establishment economics, and you know what else? Even with establishment media.

You've got the top 400 Americans owning more wealth than the bottom 150 million Americans. Most folks do not think that is right.

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.

There's issue of a corrupt campaign finance system, where big money interests and Wall Street are trying to buy elections.Those are the issues that are resonating.

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.
