Three candidates for Lt. Governor — all virtually unknown by state voters — will hold their first and only debate tonight. State Sen. Loretta Weinberg (D-Teaneck), Republican Monmouth County Sheriff Kim Guadagno, and former Kean College Professor Frank Esposito will take part in a 90-minute debate that will be broadcast on NJ 101.5 and on News 12 New Jersey. The debate is sponsored by Leadership NJ, along with 101.5, News 12, and Gannett New Jersey. It starts at 8PM from Monmouth University.
