I see myself in the mold of Rin Tin Tin. It didn't go to his head either.

I think George W. Bush has a warm, engaging personality. But, you know, the presidency is more than just a popularity contest.

If we don't succeed, we run the risk of failure.

Our world faces a true planetary emergency. I know the phrase sounds shrill, and I know it's a challenge to the moral imagination.

The Bush-Cheney administration had betrayed some basic American values. So there was hunger for change.

The first less is this: take it from me, every vote counts.

The Internet empowers individuals to play a more active role in the political process, as Obama's campaign has manifested.

I took the initiative in moving forward a whole range of initiatives that have proven to be important to our country's economic growth, environmental protection, improvements in our educational system.
