You have to think anyway, so why not think big?

I felt I had to give back to our wonderful country which has been so good to me and to my family.

I am pro-life. I am also supportive of health savings accounts, which ensure that women have the freedom to control their own health-care decisions, among numerous other reforms - like purchasing across state lines - to give Americans more control over their own health care.

I was relentless, even in the face of total lack of encouragement, because much more often than you'd think, sheer persistence is the difference between success and failure.

I also notice the very nasty commercials that Hillary Clinton do on me in so many different ways, which I don't do on her. Maybe I'm trying to save the money.

I think I have a big advantage. But it's certainly a three-person race. And you have a couple of other people that are very talented there too. So we have a five-man race. And I think that it's going to be not easy. I have a big advantage. But a long way from being won.

We have to be much tougher. We have to be much stronger than we've been.
