The 2009 Los Angeles mayoral election took place on March 3, 2009. Incumbent mayor Antonio R. Villaraigosa was re-elected overwhelmingly and faced no serious opponent.[1] Villaraigosa would have faced a run-off against second place-finisher Walter Moore had he failed to win a majority of the vote.[2] Villaraigosa won the election despite having generally unfavorable approval ratings. He was credited with winning because more well-known and better-funded candidates, such as developer Rick Caruso, declined to run.[3]
Municipal elections in California, including Mayor of Los Angeles, are officially nonpartisan; candidates' party affiliations do not appear on the ballot.[4]
