The four previous GOP debates have produced their share of memorable quotations, thanks in no small part to Donald Trump's apparent willingness to say practically anything to almost anyone. His opponents have been known to get in their share of quips, however, and this night we'll be keeping track of all of them. Keep an eye on this space for a preview of the lines everyone will be repeating tomorrow. 

Carly Fiorina on her background:

I fought my way to the top of corporate America while being called every b-word in the book.

Jeb Bush on Trump:

He's a chaos candidate. And he'd be a chaos president.

Marco Rubio on national security:

We must deal with this threat of radical Islamists, especially from ISIS, the most sophisticated terror group that has threatened the world or the United States of America.

John Kasich on the irrelevance of climate change:

They have a climate conference over in Paris, they should have been talking about destroying ISIS.

Ben Carson on why he wants "to complain a bit":

This is the first time I have spoken and several people have had multiple questions. So, please try to pay attention to that.

Ted Cruz on what's killing people:

Political correctness is killing people.

Donald Trump on civil liberties:

You talked freedom of anything you want. I don't want them using our Internet...

Rand Paul on Trump's proposals:

If you are going to close the Internet, realize, America what that entails. That entails getting rid of the First Amendment.

Carly Fiorina on gender politics:

I will just add that Margaret Thatcher once said: If you want something talked about, ask a man. If you want something done, ask a woman.

Donald Trump on whether we're safer with dictators in the Middle East: 

The Middle East is totally destabilized, a total and complete mess. I wish we had the $4 trillion or $5 trillion—I wish it were spent right here in the United States on schools, hospitals, roads, airports, and everything else that are all falling apart. 

Carly Fiorina on Trump's rhetoric:

That's exactly what President Obama has said. I'm amazed to hear that from a Republican presidential candidate.

John Kasich on America's role in world politics:

It is time we punched the Russians in the nose. We need to stand up against them.

Rand Paul on Chris Christie:

If you are in favor of World War III, you have your candidate. 

Ted Cruz on how he will fund infrastructure development:

We will build a wall that works and I'll get Donald Trump to pay for it.

Trump on why he would be great as President:

I think we need someone we can trust who is totally responsible, who knows what he or she is doing that is so powerful and so important.

Donald Trump, summing up the debate:

I thought this was an elegant group of people.

This post will be updated throughout the debate.
