Author of NPR's It's All Politics blog Mark Memmott will be liveblogging the town-hall-style debate from Hofstra University tonight, starting at 9 pm.
President Obama and Republican presidential nominee Mitt Romney meet this evening at Hofstra University on New York's Long Island for their second presidential debate. We'll be live blogging before they get going and as they take questions from audience members in what's being billed as a town hall format.
