I say that is because those are the times where sometimes you feel actually a little bit hurt. Because you feel like saying to these folks, "[Don't] you think if I could do it, I [would] have just done it. Do you think that the only problem is that I don't care enough about the plight of poor people, or gay people, or immigrants, or ...?"

It's good to get fresh legs in [the White house]. I think that it refreshes our democracy.

As has been well documented, I smoked pot as a kid, and I view it as a bad habit and a vice, not very different from the cigarettes that I smoked as a young person up through a big chunk of my adult life. I don't think it is more dangerous than alcohol.

The future belongs to young people with an education and the imagination to create.

If you don't have any fresh ideas, then you use stale tactics to scare the voters. If you don't have a record to run on, then you paint your opponent as someone people should run from. You make a big election about small things.

In a world of complex threats, our security and leadership depends on all elements of our power - including strong and principled diplomacy.
