The debate is on CNN; Wolf Blitzer is moderating. (The TV-free can watch online here.) Things kick off at 8 p.m. eastern time, but we’re chatting starting at 7:30.

If you’ve never participated in one of our live chats before, it’s a free-form, real-time conversation, like watching the debate with a bunch of politics nerds. It’s fun, we promise.
