Here's a guide to get you up to speed on the Republicans' second showdown, and be sure to tune in tonight for Daily Intelligencer's liveblog and complete debate coverage. More here:
  1. When and where is this debate being held?
    Wednesday, September 16, from 8 p.m. to 10 p.m. EST at the Ronald Reagan Presidential Library in Simi Valley, California.
  2. I just remembered I don't have cable.
    Not a problem. While the Fox News livestream was down for much of the last debate, CNN has vowed that everyone will be able to watch tonight's show online and via their apps, even if they don't have a cable subscription. "CNN will be live streaming the GOP debate ... online and across CNN’s mobile platforms without authentication. Users won’t have to log-in to see the stream, it will be available as soon as they visit or access one of our apps," CNN told Fortune.
  3. Which moderator will Republicans be angry at after this debate?
    Probably conservative radio talk-show host Hugh Hewitt. Jake Tapper and Dana Bash will get some flak if they pursue a Megyn Kelly–esque line of questioning, but Republicans have lower expectations for the CNN journalists. Hewitt, who refers to his show as "Na­tion­al Pub­lic Ra­dio for con­ser­vat­ives," is known for asking Republicans tough questions, but he's already tangled with the front-runner.
  4. I'd like to see more of Chris Christie and Rand Paul shouting at each other.
    CNN is trying to make that happen. "What the team and I have been doing is trying to craft questions that, in most cases, pit candidates against the other — specific candidates on the stage — on issues where they disagree, whether it's policy, or politics, or leadership," Tapper said. "Let's actually have them discuss and debate."
  5. Great. Who are Donald Trump's potential targets?
    Donald Trump, Jeb Bush, Scott Walker, Ben Carson, Ted Cruz, Marco Rubio, Mike Huckabee, Rand Paul, John Kasich, and Chris Christie — plus Carly Fiorina. Following her impressive performance in the undercard debate last month, Fiorina lobbied CNN to let her move up to the main event. The network changed its criteria earlier this month, ostensibly because there were fewer available polls than expected. Fiorina just happened to be the only additional candidate who qualified under the new rules.
  6. Eleven candidates doesn't sound sufficiently ridiculous. Aren't you forgetting somebody?
    Rick Santorum, Bobby Jindal, George Pataki, and Lindsey Graham will be in the so-called "kids' table" debate from 6 p.m. to 7:45 p.m EST. Rick Perry was invited to participate, but he ended his campaign last week. Jim Gilmore was excluded this time because he's polling below one percent, which would be sad if he were actually campaigning.
  7. What are the ground rules?
    Candidates will have one minute to answer each question and 30 seconds for a rebuttal if they're mentioned by another candidate. CNN may use video clips from the undercard debate, like Fox News did last month.
  8. Has CNN come up with some flashy visual gimmick?
    As far as we're concerned, no CNN event is complete without a hologram, but President Reagan's Air Force One is a pretty good consolation prize. CNN built the debate stage on scaffolding so the airplane — which you can tour if you visit the Reagan Library — serves as the backdrop for the debate. Start working on your tasteless "missing plane" jokes now!
  9. How are the candidates preparing?
    While Trump advisers are going to help him brush up on military and foreign-policy issues, he claims, once again, that he isn't cramming for the debate. "I've been prepping for 30 years," he told The Wall Street Journal. As for the rest of the field, they've vowed to be more aggressive this time around, since it's now clear that Trump is more than the GOP's summer fling.
  10. How Reagan-y will this debate be, on a scale of one to going on an all-jelly-bean diet?
    Almost unbearably Reagan-y. The former president and GOP saint came up 14 times in the last debate, when the candidates weren't standing in front of a 152ft symbol of his presidency. In preparation, PolitiFact has released a list of common ways modern Republicans distort Reagan's positions. Candidates have already started squabbling over who was closest to the former president. John Kasich makes a pretty persuasive argument in this video about campaigning for Reagan during the 1976 convention.
