Debates this election season have given many Americans perfect excuses to throw a house party. West Side bureau contributor Ian Fullerton reports that about 75 hipsters in Chicago's Logan Square neighborhood took the house-party ritual to a new level during last night's vice-presidential skirmish.

As the candidates took the stage, smoke from a barbeque momentarily spoiled the view. "It's starting," someone shouted to the audience, mostly alumni and students of the School of the Art Institute of Chicago. "Hey, it's Tina Fey!" another student yelled as Alaska Gov. Sarah Palin appeared. By the time the Republican veep hopeful made her third reference to John McCain as a "maverick," someone else bellowed, "Everybody drink!"
