Global warming is a matter of national security. Will we live in a world where we must fight our neighbors for fresh water and food? Or will we take the lead now and leave to our children and grandchildren a world better off than the one we inherited from our parents?

Veterans have had a long record of leaning towards the Republican Party. I think that's changing. I think that President Obama has the strongest record with veterans among any president in my lifetime.

The time has passed in America when this party can be the party of compassion and let the executive branch run foreign policy. It won't work. We have to be the party that can stand toe to toe with George W. Bush on national security, as well as the party of compassion.

Working together, we can build a world in which the rule of law - not the rule of force - governs relations between states. A world in which leaders respect the rights of their people, and nations seek peace, not destruction or domination. And neither we nor anyone else should live in fear ever again.

I'm pro-choice, pro-affirmative action, pro-environment and pro-labor. I was either going to be the loneliest Republican in America or I was going to be a happy Democrat.

You have to take a plan that might work and make it work

I've forgotten more about national security than George W. Bush will ever learn.
