You know, back in the '70s — I remember the '70s, we were told there was global cooling. And everyone was told global cooling was a really big problem. And then that faded.

You don't hear me lambasting, engaging in personal attacks, getting nasty. I don't think that belongs in politics.

I would note that the scripture tells us, "you shall know them by their fruit." We see lots of "campaign conservatives." But if we're going to win in 2016, we need a consistent conservative, someone who has been a fiscal conservative, a social conservative, a national security conservative.

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

The more liked you are in Washington, the less liked you are in the rest of America, and vice versa.

For most of his life, Donald Trump has described himself as very pro- choice and as a supporter of partial birth abortion. Right now today as a candidate, he supports federal tax payer funding for Planned Parenthood. I disagree with him on that.

It is very simple to be likeable in Washington. You just go along to get along. You just do what your leadership wants.
