It’s that time again -- time for another Republican presidential primary debate. The fifth one is queued up for Tuesday night, so get ready to watch the still-sizeable GOP field sound off about national security issues in Las Vegas.

The main debate starts at 8:30 p.m. EST and the undercard starts at 6 p.m. EST, so you may be in for a long night if you’re watching both events.
