NEW YORK - The Democratic mayoral candidates made their last-ditch efforts to win the primary during a televised debate Tuesday night.

Polls show that Public Advocate Bill de Blasio has surged ahead in recent weeks, with Bill Thompson hanging onto second and Christine Quinn sliding into third. Early front runner Anthony Weiner has fallen into fourth.

The five candidates laid out their potential agendas, and challenged each other on hot-button issues, including stop-and-frisk, immigration and education.

The primary election is Tuesday, Sept. 10. The Democratic and Republican winners will then face off during the General Election in November.
