I think the debate was really some powerful moments of clarity. We saw that Donald Trump, substantively, has the same issues on issue after issue as Hillary Clinton. He agreed with Hillary Clinton on Libya, toppling the government in Libya. That led directly to Benghazi, led to handing that country over to radical Islamic terrorism.

Republican party leaders have been worrying about the damage a [Donald] Trump nomination could do to the party, but also what might happen if he left the GOP and took his supporters with him. But Trump said he would stay a Republican and do everything in his power to beat Hillary Clinton.

I believe you [Donald Trump] know politicians better than I do because for 40 years you've been funding liberal Democratic politicians.

If we want to defend the country, we have to defend against who's coming in.

The judgment that every voter is making of every one of us [running for presidency] who has the experience, who has the vision, who has the judgment to be commander in chief. That is the most important decision for the voters to make. That's a standard I'm held to. And it's a standard everyone else is held to.

Since there are no absolutes, when it's convenient, you change the rules. Do we know any politicians that have done that?

One of the most troubling aspects of the Rubio-Schumer Gang of Eight Bill was that it gave President [Barack] Obama blanket authority to admit refugees, including Syrian refugees without mandating any background checks whatsoever. Now we've seen what happened in San Bernardino. When you are letting people in, when the FBI can't vet them, it puts American citizens at risk.
