Our example - and commitment - to freedom has changed the world. But along with the genius of our Declaration of Independence, our Constitution, and our Bill of Rights, is the equal genius of our economic system. Our Founding Fathers endeavored to create a moral and just society like no other in history, and out of that grew a moral and just economic system the likes of which the world had never seen. Our freedom, what it means to be an American, has been defined and sustained by the liberating power of the free enterprise system.

Like the vast majority of Americans, I've opposed same-sex marriage, but I've also opposed unjust discrimination against anyone, for racial or religious reasons, or for sexual preference. Americans are a tolerant, generous, and kind people. We all oppose bigotry and disparagement. But the debate over same-sex marriage is not a debate over tolerance. It is a debate about the purpose of the institution of marriage and it is a debate about activist judges who make up the law rather than interpret the law.

What I can tell you is I'm not running for president. I'm not going to run for president. I'm going to support one of these four people to be our nominee. I'm supporting three of them right now. And that means that we're going to get one of those people as our nominee.

There's no question but that a nuclear Iran, a nuclear-capable Iran is unacceptable to America. It presents a threat not only to our friends but ultimately a threat to us to have Iran have nuclear material, nuclear weapons that could be used against us or used to be threatening to us.

Iran's nuclearization is the greatest single national security threat America faces.

We have always been a nation that has celebrated success of various kinds. The kid that gets the honor roll, the individual worker that gets a promotion, the person that gets a better job. And in fact, the person that builds a business. And by the way, if you have a business and you started it, you did build it. And you deserve credit for that.

I happen to believe that if we want to replace a lifetime politician like Barack Obama, who had no experience leading anything... We've got to nominate a leader if we're going to replace someone who is not a leader.
