The presidential candidates on the main stage of tonight's debate will get 1 minute to answer each question, according to CNN. Each candidate will also have 30 seconds to respond to another candidate's answer if his or her name is mentioned. Moderator Jake Tapper, acknowledging that it will be a challenge to enforce the rules for 11 candidates, said "I'm just going to do the best I can. I don't know if bringing out a whip and a lion tamer's chair would help but we're just going to try to enforce the rules and ask the questions and see what happens."
NPR's tally of the first Republican debate showed frontrunner Donald Trump got more air time than any of the other candidates (10 minutes and 30 seconds), followed by Jeb Bush at 8:33. Rand Paul got the least at 4:51. Fox had said it would try to give the candidates equal time to speak.
Check back here tonight for a running tally of how much air time each candidate is getting.
