The worst nightmare in the world is a radical Islamic regime with a weapon of mass destruction.

I'm for Simpson-Bowles. It doesn't raise taxes, it closes loopholes and takes the money we would give to a few people and put it on the debt.

What we're trying to look for is a process that is not responding to political pressures, but one that is responding to economic reality, because I do believe ... that it's in the best interest of the Chinese people to allow a market-based currency.

I am confident - very confident - that if I help solve this problem in a way that we won't have 20 million illegal immigrants 20 years from now, not only will I get re-elected, I can look back and say I was involved in something that was important.

I think that is the fight that we have to wage if we're to save the middle class. And I do have doubts about whether Hillary Clinton or whether any Republican candidate out there is prepared to take on the big money interests who control so much of our economy and as a result of Citizens United, our political process as well.

I think as people find out about my foreign policy, what they're going to find out is that I'm right in the mainstream of the Republican Party. I believe the number one priority of the federal government is national defense.

Some people say I'm too blunt and I'm too direct, too straightforward. I think we could use some of that in Washington, D.C.
