The 2012 presidential election is coming down to the wire, and President Barack Obama and GOP challenger Mitt Romney are set to square off once again Tuesday in their second of three presidential debates.

Tuesday night's debate will take place at Hofstra University in Hempstead, N.Y. and will take on a town hall-style format. The candidates will be grilled by undecided members of the voting public on domestic and foreign policy issues.

Obama's campaign, seeking to rebound from a dismal first debate, promised a more energetic president would take the stage Tuesday at Hofstra University in Hempstead, N.Y. Romney's team aimed to build on a commanding opening debate that gave the Republican new life in a White House race that had once appeared to be slipping away from him.
