Look, first of all, the climate is changing. I don't think the science is clear what percentage is man-made and what percentage is natural. It's convoluted.

The climate is changing, and we need to adapt to that reality.

We cannot meet 21st Century challenges with a 20th Century bureaucracy.

If we are going to solve the challenges we face, you need a President who will pursue genuine solutions day in and day out. And that is my commitment to you. We need immigration reform that will secure our borders, and punish employers who exploit immigrant labor; reform that finally brings the 12 million people who are here illegally out of the shadows by requiring them to take steps to become legal citizens. We must assert our values and reconcile our principles as a nation of immigrants and a nation of laws. That is a priority I will pursue from my very first day.

I do think that all politicians today have to be more attentive to people wanting to be heard, wanting to have more control over their lives.
