Tonight's town hall debate at Hofstra University will work a little differently than the previous presidential and vice presidential debates. Here's what to expect. 

There will be no opening (or closing) statements from President Obama and Mitt Romney; moderator Candy Crowley will introduce the candidates. Then town hall participants, undecided voters selected by the Gallup Organization, will start asking questions. Romney gets the first question.
