We've got an extraordinarily complex tax system that's full of loopholes that are exploited by special interests. I'd like to see those loopholes closed.

It's a moral imperative, it's an economic imperative, and it is a security imperative. For we've seen how spikes in food prices can plunge millions into poverty, which, in turn, can spark riots that cost lives, and can lead to instability. And this danger will only grow if a surging global population isn't matched by surging food production. So reducing malnutrition and hunger around the world advances international peace and security - and that includes the national security of the United States.

If we can’t puncture some of the mythology around austerity, politics or tax cuts or the mythology that’s been built up around the Reagan revolution, where somehow people genuinely think that he slashed government and slashed the deficit and that the recovery was because of all these massive tax cuts, as opposed to a shift in interest-rate policy - if we can’t describe that effectively, then we’re doomed to keep on making more and more mistakes.

I don't think that any economist disputes that we're in the worst economic crisis since the great depression. The good news is that we're getting a consensus around what needs to be done.

The United States will do what we must to prevent Iran from obtaining a nuclear weapon.

One of the things I think I can bring to the presidency is to make government and public service cool again.

Now, as the world's largest economy and as the world's second largest emitter, America bears our responsibility to address climate change, and we intend to meet that responsibility.
