Newsom drew voter attention with his Care Not Cash program, which was designed to move homeless people into city-assisted care.
He is currently the president in absentia of Airelle Wines Inc., which is connected to the Plump Jack Winery in Napa County.
Newsom earned between $141,000 and $251,000 in 2007 from his business interests.
The race was partisan with attacks against Gonzalez for his support of Ralph Nader in the 2000 presidential election and attacks against Newsom for contributing $500 to a Republican slate mailer in 2000 that endorsed issues Newsom supported.
San Francisco's progressive community attempted to find a candidate to run a strong campaign against Newsom.
Newsom placed first in the November 4, 2003, general election in a nine-man field.
Newsom received 41.9 percent of the vote to Green Party candidate Matt Gonzalez's 19.6 in the first round of balloting, but he faced a closer race in the December 9 runoff when many of the city's liberal groups coalesced around Gonzalez.Gavin Christopher Newsom was born in San Francisco, California, to Tessa Thomas (née Menzies) and William Alfred Newsom III, a retired state appeals court justice and attorney for Getty Oil. He is of mostly Irish descent; one of his maternal great-grandfathers, Scotsman Thomas Addis, was a pioneer scientist in the field of nephrology and a professor of medicine at Stanford University.Newsom is the second cousin, twice removed, of musician Joanna Newsom.He sponsored Proposition B to require Muni and other city departments to develop detailed customer service plans.Newsom also supported allowing restaurants to serve alcohol at their outdoor tables, banning tobacco advertisements visible from the streets, stiffer penalties for landlords, and a resolution to commend Colin Powell for raising money for youth programs that was defeated.He later reflected on his education fondly, crediting the Jesuit approach of Santa Clara that he said has helped him become an independent thinker who questions orthodoxy. Getty told the San Francisco Chronicle that he treated Newsom like a son and invested in his first business venture because of that relationship.
