Last night, ABC treated us to a full-scale GOP debate that went rather of the rails; but, of course, NBC had to get in on the action, and less than twelve hours later are partnering up with Facebook to host another debate. In case any of us (or any of you!) are up to watch it, here's the live Twitter feed, and please leave your comments. The debate is live-streaming here, and airs on TV at the local time of "Meet the Press." Enjoy, early-birds!
