in 1993 When
Tom Bradley announced he was retiring as
Mayor of Los Angeles, Riordan set his sights on the
1993 election. Riordan's tenure was marked by controversy over the
Los Angeles County Metropolitan Transportation Authority's Red Line subway's construction cost overruns. Because the overruns resulted in MTA funds being reallocated from bus funding, the
Bus Riders Union sued the city, alleging racial discrimination, resulting in a 1996
consent decree that eviscerated MTA funding for subway and
light rail construction projects. Riordan publicly stated that he regretted signing the consent decree and it was his biggest mistake as mayor. Before becoming mayor, Riordan spearheaded the city's successful
term limit ballot initiative and he was therefore term-limited from office in 2001. Riordan endorsed his adviser and friend,
Steve Soboroff, to succeed him. Soboroff, however, came in third in the non-partisan
mayoral primary election. Former California State Assembly Speaker
Antonio Villaraigosa advanced to the runoff against
James Hahn. Riordan endorsed Villaraigosa in the second round, but Hahn won and succeeded him as mayor. Four years later, Villaraigosa defeated Hahn in the 2005 rematch and became Mayor. == 2002 California gubernatorial race ==
