I would argue that we have a patriotic duty to move toward energy independence and clean energy. It is a matter of national security - energy security, climate security, economic security, job security, everything.

Asia is rising economically - and is thirsty for oil. The price pressures on oil and oil price shocks, due to Asia's economic rise, mean that all steps made now to reduce oil dependence will protect us from pain and volatility later.

Deep patriots don't just sing the song, 'America the Beautiful' and then go home. We actually stick around to defend America’s beauty -- from the oil spillers, the clear-cutters and the mountaintop removers. Deep patriots don't just visit the Statue of Liberty and send a postcard home to grandma. We defend the principles upon which that great monument was founded -- 'give me your tired, your poor, your huddled masses yearning to breathe free.'

Donald Trump's a great deal-maker with a lot of momentum and it will do a lot of damage to us. We are in grave peril and it's going to be terrible.

You can't lead anybody you don't love. You can't do it. It's not possible.

If I didn't have that deep grounding, it would be very easy for me to just be someone who is consumed with anger and hatred. And that would be Trump's great victory: to turn us into replicas of him, just on the other side of a wall screen. I refuse to let me or my family or my movement or my friends be turned into the opposite of Trump. I want to be the antidote for Trump.

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