I cannot in good conscience ask my colleagues to expend precious time and energy defending or explaining my past. We need all hands on deck, fighting for the future.

Hatred of the people who hate you, that is the opposite of being the enemy. I want to fight fire with water wherever I can.

People in red states and blue states can agree that if we can fight pollution and poverty at the same time, letting people work their way out of poverty without undermining community health, we have a moral obligation to do so.

If people leave your coalition, whose fault is it? It's your fault. You have to build a coalition that's attractive to people.

The government also has to get the public rules right. That means putting a price on carbon, so the cleaner forms of energy become more competitive. As soon as that happens, a tidal wave of new capital, innovation and entrepreneurship will flood into the clean energy space - creating new jobs and opportunities for Americans of all walks of life. We did that for the internet, with public investments in the basic system through the Pentagon, followed by rules that encouraged innovation and competition. And that is why the internet took off in the United States first.

The dirty energy crowd can be offset only by the power of the rising clean energy sector and the American people, aroused across party lines.

We actually need conservatives to be better conservatives and we need liberals to be better and stronger liberals.
