Gavin Newsom wins Democratic primary for lieutenant governor
Newsom, 43, who was a candidate for governor until dropping out of the race in November, was a late entrant into the lieutenant governor's race.
He made national headlines in 2004 when he authorized marriage licenses for gay and lesbian couples. The state Supreme Court eventually authorized same-sex unions, but that law was overturned when voters passed Proposition 8 in 2008.
Hahn conceded to Newsom on Tuesday night.
