I don't think a party can aspire to be the majority party if it's the old white guy party.

I used to be a conservative and I watch these debates and I'm wondering, I don't think I've changed, but it's a little troubling sometimes when people are appealing to people's fears and emotion rather than trying to get them to look over the horizon for a broader perspective and that's kind of where we are.

We have huge national security issues in this country, and the United States Senate ought to be pushing President [Barack] Obama towards the proper policies that right now are a complete disaster based on his policies.

As president, I will keep you and our country safe, secure, and free.

I don't think the science is clear of what percentage is man-made and what percentage is natural. It's convoluted, for the people to say the science is decided on this is really arrogant, to be honest with you.

A third of our kids, after we spend more per student than any country in the world other than a couple rounding errors, 30 percent are college- and/or career-ready.

If we`re going get back into hypotheticals, I think it does a disservice to a lot of people that sacrificed a lot.
