Welcome to the eighteenth debate of the Republican primary!

This debate is in Tampa, Florida and NBC News’ Brian Williams is moderating. For those of you without TV, you can watch online here.

The debate starts at 9 p.m., but we’ll be liveblogging here ten or fifteen minutes before the action starts.

If you’ve never participated in one of our liveblogs, it’s like watching the debate with a bunch of politics nerds. It’s fun. We promise.
