What animates me in politics are the economic issues of opportunity.

Climate change is the perfect pseudoscientific theory for a big government politician who wants more power. Why? Because it is a theory that can never be disproven.

The specific question was visa overstays.Current federal law requires a biometric exit-entry system when you come in on a visa. And the [Barack] Obama administration is just ignoring federal law. Forty percent of illegal immigration is not people who cross the borders illegally. It's people who come legally on a visa and never leave.

I care a heck of a lot more about America than I do about any political party.

I've spent my whole life fighting for free-market principles and the Constitution. That's not going to change.

I think it's an enormous blessing to be the child of an immigrant who fled oppression, because you realize how fragile liberty is and how easily it can be taken away.

The grass roots are energized because the absolutely highest priority in the country in November is to defeat Barack Obama. I have spoken with literally thousands and thousands of tea-party activists - I have yet to meet a single tea-party leader that is not going to vote for Mitt Romney.
