Republican debate as it happened: Candidates face off in Colorado for third presidential debate

That's a wrap for tonight's debate. Thanks for following!

John Kasich showed early fire in the debate, but perhaps the biggest winner of the night was Marco Rubio, who was prepared for all questions and attacks sent his way. For a second debate in a row, Donald Trump seemed to shrink away, barely getting airtime. However, it remains to be seen who will be chosen as the winner of tonight's debate by critics and voters.

The candidates are giving their 30 seconds closing speeches. As the third GOP debate starts closing up, it looks like several candidates shined, while others did not take advantage the platform the debate gives them.

We don't have a healthcare crisis here. We have a health crisis.

-Mike Huckabee

After Jeb Bush is asked about gambling in regards to fantasy football, Christie responds: "We have ISIS and al-Qaeda attacking us and we're talking about fantasy football!"

Trump, who has not received a lot of airtime during the debate, is not happy and he let everyone know on Twitter.

The moderators at CNBC appear to be having an issue reining in the candidates. Many are speaking out of turn and for longer than the allotted time.

Donald Trump attacks Super PACs, saying they are far too influential. Rubio backs him up, adding, "The Democrats have the ultimately super PAC -- it's called the mainstream media."

Ben Carson hit back at questions regarding his partnerships with Costco and a drug company that claimed it could cure cancer, among other diseases. He also defended his views on same-sex marriage. "You don't understand my views on homosexuality. I believe our Constitution protects everybody," he said.

You find a Democrat that's for cutting spending by $10, I'll give them a warm kiss.

-Jeb Bush

Two of the three Democratic candidates, Hillary Clinton and Martin O'Malley, are tweeting along to the #GOPDebate.

Donald Trump, when asked about going bankrupt, said he used the law to his advantage and placed a lot of blame on the downfall on Atlantic City's economy.

Asked about the debit limit, Senator Ted Cruz decided to go on the attack, calling CNBC liberal media that is working to tear down the GOP candidates. Chaos ensued and the question was never answered.

The only female GOP candidate, Carly Fiorina, says she will reform the tax code from 76,000 pages to 3 pages.

Donald Trump none to happy after moderator John Harwood says he has about as much a chance of succeeding with his tax plan as he does flying by flapping his arms up and down.

The candidates are being introduced as the main debate begins. The moderators ask what the candidates believe are their biggest weaknesses and what they are doing to fix them.

CNBC reported that voters have announced that Lindsey Graham won the minor debate. It remains unclear if that will be of any benefit to Graham. He has continuously polled poorly despite winning the second GOP debate.

The second batch of candidates are arriving for the main debate, which is set to start at 8pm ET/12am GMT.

The minor debate is wrapping up as the four candidates give their 30 second final speeches. Lindsey Graham, who appeared to have a fire lit inside him tonight, took a jab at Donald Trump during his final comments. "Somebody said on the bill of a cap, 'Make America great again.'America IS great."

The candidates are asked what three apps they use the most.

• Bobby Jindal: Doesn't have a smartphone. Still owns a Blackberry.
• Rick Santorum: NFL, MLB and Wall Street Journal
• George Pataki: Uber and Twitter
• Lindsey Graham: Fox News

Santorum shakes his head as Pataki says that vaccines are the right way to go. Pataki says he wants Republicans to embrace technology and science, particularly in relation to global warming.

While Pataki has made several pointed attacks towards Jindal, these four candidates seemed set on attacking President Barack Obama and Democratic candidates Hillary Clinton and Bernie Sanders.

Lindsey Graham is asked if he's in the wrong party based on his policies regarding climate change and illegal immigration. He said he wants to fix the problems. Graham said he would not deport the 11 million undocumented immigrants in the US, but instead wants to work on comprehensive immigration reform.

Less than 25 minutes into the first minor debate, George Pataki used a question on cybersecurity to attack Democratic frontrunner Hillary Clinton and her server scandal. Pataki said the scandal makes Clinton ineligible to run for president.

We're going the way of Europe. The left is turning the American dream into the European nightmare.

- Bobby Jindal on the budget deal

Bobby Jindal deflects when asked if he would agree to the budget or decide to shut down the government. His response: It's a false choice. If it were up to him, he'd push conservative budget agenda and get things done.

First question relates to voters supporting candidates considered to be "outsiders" in Washington DC. The first four candidates, who have all worked in government before, discuss how they plan to work as outsiders with their insider knowledge.

Two hours before he hits the stage, former Florida Governor Jeb Bush took to Twitter to tell supporters, "I've delivered."

The first four candidates--Lindsey Graham, Bobby Jindal, George Pataki and Rick Santorum--have entered the stage. The rules, much like the previous two debates, give candidates 60 seconds to answer questions and 30 seconds for rebuttals.

The first debate is just minutes away from beginning. Each debate will be broadcast on CNBC. CNBC digital subscribers will be able to watch the debate online at CNBC.com, the mobil app and on Apple TV. For those hoping to listen in on the radio can tune in to SiriusXM channel 112.

The relatively unknown Ohio governor John Kasich came out swinging against his GOP opponents during a pre-debate rally in Ohio on 27 October. Kasich said he has "had it" with what he called the "crazy" policies being touted by his fellow Republican candidates.

"Do you know how crazy this election is?" he said. "I've about had it with these people."

Kasich's spokesman Chris Schrimpf told reporters that the candidate's new attitude was a new decision in strategy ahead of the third Republican debate.

"I'm going to have call it like it is as long as I'm in this race," Kasich said. "I'm done with being polite and listening to this nonsense, and it's time we educate the American people about the consequences of very bad choices."

The latest poll from CBS and the New York Times revealed retired neurosurgeon Ben Carson has pulled ahead of frontrunner Donald Trump, 26% to Trump's 22%. The two are trailed not so closely behind by Marco Rubio (8%), Jeb Bush (7%) and Carly Fiorina (7%). The remaining candidates polled the following:

• Ted Cruz, Mike Huckabee, John Kasich and Rand Paul each nabbed 4%.
• Lindsey Graham grabbed 2%.
• Chris Christie and Rick Santorum scored 1%.
• Bobby Jindal, George Pataki and Jim Gilmore all scored below 1%.
