2016 Presidential Race: Everything You Need To Know About the First GOP Debate

The anticipation is high and the stakes are even higher.

— -- The anticipation is high and the stakes are even higher.

Fox News unveiled the participants on Tuesday, and we are now learning details about what exactly is going to happen when the clock strikes 9 p.m. on the east coast.

Here's everything you need to know:

WHO'S ON STAGE?

WHO'S MISSING?

Former Texas Gov. Rick Perry just missed the stage by 1.4 percent and is sitting in 11th place, according to an ABC News analysis of the five national polls used by Fox News. Notably, Rick Santorum, the 2012 winner of the Iowa caucuses and runner-up to eventual nominee Mitt Romney, will also be missing from the stage. The former Pennsylvania Senator says that national polls shouldn't be used because it strips early states like Iowa and New Hampshire from their influential role.

THE RULES

Each candidate will have one minute to respond to a question and 30 seconds to give rebuttals. Bret Baier, Megyn Kelly and Chris Wallace from Fox News will tag team moderating the ten-person GOP presidential field. Fox News has also said that they will try to give all 10 candidates equal time to talk on the stage, which would equal roughly 10 minutes per candidate. Wallace pointed to his binder of debate questions in an interview with the Washington Post, saying, “I’ve got some doozies in there.”

PACKING THE ARENA

Rick Gorka from the Ohio Republican Party says that there will be about 5,000 people in the area to watch the debate – the largest crowd in debate history, he says. Gorka says the party got more than 7,000 requests for tickets. “It would have been harder to get tickets to this debate than to the NBA Finals,” he said.

FACEBOOK "LIKES" THE GOP DEBATE

No matter how many fans these candidates have on Facebook, the social media network will play an important role in Thursday night’s debate. The general public will be able to send in Facebook posts and videos during the debate asking their questions – and Fox will use them to ask and frame questions throughout the debate.
