Tonight at 8 p.m. eastern time seven Republican candidates running for president will take the stage in Las Vegas for the fifth debate in the last six weeks.

And what would a Republican debate be without a Fix live blog? (Answer: It would be, somehow, empty. Like “Two and a Half Men” without Charlie Sheen. Or Van Halen without David Lee Roth.)

Starting around 7:30 p.m. — we like to warm up to avoid injury — the Fix posse will be detailing every quote and note from the debate. If you’ve never participated in a Fix live blog before, there’s no time like the present. It’s “Mystery Science Theater 3000” and the “McLaughlin Group” rolled into one. Sort of.

Come. Comment. Hang out. It’s the only way to watch a debate!
