The candidates have agreed to participate in a debate Sept. 29 sponsored by KPCC Public Radio and La OpiniÃ³n Spanish-language newspaper.
While the first debate between the two rivals was a "face off" aired on television stations across the state, this round will be limited to candidates "sounding off" on the issues.
The 1 p.m. debate will air on the radio station as well as www.scpr.org. It will be broadcast live from KPCC's Pasadena studios.
