Los Angeles City Councilmen Marvin Braude and Zev Yaroslavsky have done something that members of the city's small, rather collegial governing body have not done in at least a quarter of a century. They endorsed a challenger over an incumbent--Michael Woo over 13th District veteran Councilwoman Peggy Stevenson--in a council race. "Peggy Stevenson has been a reliable vote for special interests and City Hall lobbyists, to the detriment of my district and to the detriment of the city," Yaroslavsky said. Braude added: "Mrs. Stevenson is not one of the hard workers on the council. She is not one who has initiated anything or contributed to the debate."
