You don't hear me lambasting, engaging in personal attacks, getting nasty. I don't think that belongs in politics.

I think data is incredibly powerful for understanding what people are thinking and for allocating resources.

I had a back-and-forth where I asked Donald Trump, is it true or false that he said the government should pay for everyone's health care? He said it's false. Listen, within minutes, we put out a video just contrasting what he said there with video of him just a few months earlier saying exactly the opposite.

Any Republican, especially any conservative, expects the media to be hostile. That's just the reality of being a Republican. You've got to be prepared to deal with that.

If you can stitch together that kind of coalition with young people, bringing together conservatives and evangelicals - and I will tell you, in Iowa, we also won Reagan Democrats, working-class voters.

I would note that the scripture tells us, "you shall know them by their fruit." We see lots of "campaign conservatives." But if we're going to win in 2016, we need a consistent conservative, someone who has been a fiscal conservative, a social conservative, a national security conservative.

I can tell you is all nine of the people here [on debates] would make an infinitely better commander in chief than Barack Obama or Hillary Clinton.
