Former state Sen. Nate Holden, one of two candidates in the Los Angeles City Council’s 10th District runoff election, announced that several former rivals have endorsed him. Six losing candidates in the April 14 primary election--including Kenneth Orduna, an aide to Rep. Mervyn M. Dymally (D-Calif.); Arthur Song Jr., an attorney, and Denise Fairchild, a former city commissioner--threw their support behind Holden. They said they are in agreement with Holden on issues and priorities for the district. At a press conference at his headquarters, Holden also received the endorsement of Assemblyman Mike Roos (D-Los Angeles) and Los Angeles City Atty. James K. Hahn, whose father, Supervisor Kenneth Hahn, already has endorsed Holden. In the primary election, Holden received 21% of the vote, more than any of the other dozen candidates. Los Angeles City Commissioner Homer Broome, the choice of Mayor Tom Bradley, placed second with 16%. The runoff vote is set for June 2.
