The second U.S. Presidential debate kicks off in about a half-hour (9PM ET, 6PM PT, 0100 UTC) from Hofstra University in Hempstead, New York. Incumbent Barack Obama and challenger Mitt Romney will take questions from an audience of allegedly undecided voters. A live stream of the event will be available from a number of sources (C-SPAN, CNN, ABC, and PBS), and it will be broadcast nationally on the major networks. The flash-less and television-less can use rtmpdump to catch the debate from C-SPAN. It won't preempt the more important telecasts, like playoff baseball. Candidates from smaller parties again went uninvited (e.g. Gary Johnson from the Libertarians, Jill Stein from the Greens, Virgil Goode from the Constitution Party, and Rocky Anderson from the Justice Party). In fact, Jill Stein was arrested for attempting to enter without credentials (her side of the story). Assuming she's out of jail by Thursday, she and Gary Johnson will be participating in an online debate hosted by IVN.us. While tonight's debate is in progress, Politifact will be fact-checking the candidates in real-time (while CNN has demonstrated their journalistic capabilities with a debate drinking game). Feel free to weigh in with your commentary on the debate below — it would be helpful to provide timestamps or other context when referring to particular statements. As before, we're posting this here in a vain attempt to keep the political discussion out of other story threads tonight. If either of the candidates spontaneously concedes the election or catches fire, we'll do our best to update you.
