My strong preference has always been to legislate when I can get legislation done.

I always enjoy watching Republicans compliment Bill Clinton now, because at the time, I'm sure he didn't feel a lot of the love.

I will work every single day to make sure that America continues to be the greatest nation on earth.

And so you [young Americans]need to be the Idea Generation. The generation who's always thinking on the cutting edge, who's wondering how to create and keep the next wave of American jobs and American innovations, who's figuring out how to out-compete the Idea Generations of Indias and Chinas of the world.

One of the things I think we have to do is make sure that college is affordable for every young person in America. And I also think that we're going to have to rebuild our infrastructure, which is falling behind, our roads, our bridges, but also broadband lines that reach into rural communities. So there are some things that we've got to do structurally to make sure that we can compete in this global economy. We can't shortchange those things. We've got to eliminate programs that don't work, and we've got to make sure that the programs that we do have are more efficient and cost less.
