We have to transform our energy system.

We need a strategy. And the goal is to bring millions of people together.

It's not in the interest of the corporations who own the networks to actually be educating the American people so that are debating the real issues. It's much better to deflect attention away from issues and get into the story of the day.

When the media worries about what Hillary’s hair looks like or what my hair looks like, that’s a real problem. We have millions of people who are struggling to keep their heads above water, who want to know what candidates can do to improve their lives, and the media will very often spend more time worrying about hair than the fact that we’re the only major country on earth that doesn’t guarantee health care to all people.

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.

I would love to have the endorsement of every progressive organization in America. We're very proud to have received recently the endorsement of MoveOn.org. We've received the endorsement Democracy for America. These are grassroots organizations representing millions of workers.
