The second presidential debate is Tuesday night, which means it's time to preview the policy and political story lines to watch with Nia-Malika Henderson, Wonkblog's Ezra Kein and The Fix's Chris Cillizza.
Watch it now and tune in tomorrow morning on the Fix for a Google+ Hangout with Chris and Ezra's Wonkblog and Fix colleagues, including Dylan Matthews, Aaron Blake and Sean Sullivan, at 10:30 a.m. ET to recap the debate. Want to ask them a question? Tweet it using #WonkFix.
