CNN's second Republican primary debate airs Tuesday evening at 8:30 p.m. ET, with an "undercard" event for the four lowest-polling candidates scheduled for 6:00 p.m. ET.
The debate—the fifth of at least a dozen—will take place at The Venetian in Las Vegas, Nevada. CNN anchor Wolf Blitzer will be the lead moderator, with help from the network's lead political correspondent Dana Bash, and conservative radio host Hugh Hewitt.
The candidates who qualified for the main event, based on a combination of polling criteria, include: Donald Trump, Ben Carson, Ted Cruz, Marco Rubio, Jeb Bush, Carly Fiorina, Chris Christie, John Kasich, and Rand Paul. The undercard debate will feature Mike Huckabee, Chris Christie, John Kasich and Rand Paul.
The undercard event will feature Mike Huckabee, Rick Santorum, George Pataki, and Lindsey Graham.
Both debates will air live on CNN, CNN.com, and the network's mobile app.
SiriusXM radio subscribers can listen on the CNN simulcast on channel 116.
