I'm blown away. I'm flabbergasted the president [Barack Obama] made the phone call to Rouhani after 30-plus, `79, 33 years or so. And there's a reason we haven't negotiated with Iran, because they're state-sponsored terrorists. They're the central bank for terrorism around the world.

We will continue to deepen our engagement using every element of American power - diplomacy, military, economic development, the power of our values and our ideals.

No deal means a greater chance of more war in the Middle East.

The American people recognize that their careers or their kids' careers are going to have to be more dynamic. That they might not be working at a single plant for 30 years. That they might have to change careers. They might have to get more education. They might have to retool or retrain. And I think the American people are game for that.

I believe in term limits for presidents because I think that there is no doubt I'm a better president now than I was when I start.

I favor legalizing same-sex marriages, and would fight efforts to prohibit such marriages.

I very much believe in reforming the tax system.
