Our intervention to destabilize the Assad regime has really made the chaos worse in Syria. And if you were to get rid of Assad today, I would actually worry about the 2 million Christians that are protected by Assad.

Let's make the haystack smaller. Let's say for a while, until we can figure out who's coming, who's going, and who's overstayed their visa, let's have extra scrutiny and figure out what's going on, because there's a whole segment of the world that is intent on sending people here to attack us.

I don't like the idea of telling private business owners. I abhor racism. I think it's a bad business decision to ever exclude anybody from your restaurant. But at the same time I do believe in private ownership. I think there should be absolutely no discrimination in anything that gets public funding.

I think that there is a bipartisan consensus that's incorrect that we should have the whole world be in NATO. For example, if we had Ukraine and Georgia in NATO - and this is something McCain and the other neocons have advocated for - we would be at war now because Russia has invaded both of them.

The power to tax and spend is restricted by the enumerated powers.

The current budget that the Republicans are looking at never balances. How can that be fiscally responsible? And how can we look at the public with a straight face and say yes we ran on balanced budgets.

I think it's a real debate how big NATO should be and whether or not it's more provocative than good. Whenever there's a war fought, our soldiers fight it and our dollars pay for it. And, really, our decisions need to be about our national security.
