(Associated Press file photo) Then-California Gov. Jerry Brown, left, and Howard Jarvis, tax reformer and executive director of the California Apartment Owners' Association, one of the proponents of Proposition 13, during a news conference in Los Angeles on July 19, 1978. Proposition 13, the 1978 tax revolt initiative, placed strict caps on property tax increases that are still in place today. Although Brown opposed it, his embrace of the measure once it passed earned him the endorsement of Jarvis.
