The Republican promise is for policies that create economic growth. Republicans believe lower taxes, less regulation, balanced budgets, a solvent Social Security and Medicare will stimulate economic growth.

If Americans were attacked, it does change the equation. The problem is, is that with regard to this is there've been horrendous killings of civilians with conventional weapons.

As commander-in-chief, I will do whatever it takes to defend America. But in defending America, we cannot lose what America stands for.

When I asked the president [Barack Obama], can you kill an American on American soil, it should have been an easy answer. It's an easy question. It should have been a resounding and unequivocal no. The president's response, he hasn't killed anyone yet.

I'm a different kind of Republican. I've introduced a five-year balanced budget. I've introduced the largest tax cut in our history. I stood for ten and a half hours on the Senate floor to defend your right to be left alone. But I've also gone to Chicago. I've gone to Detroit. I've been to Ferguson, I've been to Baltimore, because I want our party to be bigger, better and bolder...

I think really that you shouldn't run as a conservative if you're not.

For example, the use of chemical weapons [in Syria]- some on the Democrat side have said well, this encourages the North Koreans to use chemical weapons against our troops.
