I don't believe we need a good conservative judge, and I don't believe we need a good liberal judge. I subscribe to the Justice Potter Stewart standard. He was a justice on the Supreme Court of the United States. And he said the mark of a good judge, good justice, is that when you're reading their decision, their opinion, you can't tell if it's written by a man or woman, a liberal or a conservative, a Muslim, a Jew or a Christian. You just know you're reading a good judicial decision.

I think there has been an exaggeration [of the terrorist threat].

I have a plan to protect the environment so that we leave this place in better shape to our children than we were handed it by our parents.

If America is at war, I won't speak a word without measuring how it'll sound to the guys doing the fighting when they're listening to their radios in the desert.

We have staring us in the face here an enormous opportunity to actually find a way forward to have peace and stability in Syria, to reconstitute it. It'll take years to do that. This will not be an easy fight even with concerted coordination with respect to ISIL. But it is far more doable with that kind of approach than otherwise.

We do have to take the long-term view. And long term, the question to ask ourselves is whether America should attack others pre-emptively, whether she should embroil herself in wars far away from our soil, and try to bring democracy by force to the rest of the world.

America must always be the world's paramount military power. But we can magnify our power through alliances.
