Municipal elections in California, including Mayor of Los Angeles, are officially nonpartisan; candidates' party affiliations do not appear on the ballot.[2]
Incumbent John Clinton Porter announced that he would be running for re-election.[3] He was challenged by Los Angeles County Supervisor Frank L. Shaw, former Mayor George E. Cryer, and State Assemblymember Charles W. Dempster.During the election, Shaw's citizenship came under question, as he had been born in Warwick, Ontario, Canada, and his birth records were not found.[4] Because of his birth records, a complaint was filed to try to prevent him from becoming mayor, asserting that he was still only a citizen of Canada and not a citizen of the United States.[5] [6] In the runoff election, Shaw beat Porter by a comfortable margin.[7]
