What question would you ask the candidates at Tuesday's debate?

President Barack Obama and Republican nominee Mitt Romney are set to tussle once again this Tuesday, at a town hall-style debate at New York's Hofstra University. The 90-minute debate, moderated by CNN's Candy Crowley, will feature questions from undecided voters. Those questions, both on foreign and domestic policy, will be selected by the Gallup polling organization.

NBC News wants to know what you'd ask the candidates and why.

Are you focused on job growth, concerned about women's issues, or wondering about a nuclear Iran? What issue matters most to you? 

We'll curate your responses and decipher any emerging trends. Check back with us before the debate to see what's on the minds of NBC News users.
