the Clean Trucks Program also provides for improved working conditions, wages and benefits for port truckers. Prior to the Clean Air Action Plan, she had already shifted about 35% of goods to be moved during off-peak hours. Hahn also helped advance redevelopment projects at the Port of Los Angeles in both San Pedro and Wilmington. On the City Council, Hahn was a major proponent of gang prevention, intervention, and suppression programs. She led the campaign to pass Measure A, which would have dedicated a sustainable revenue stream for those programs, but fell just shy of the two thirds percentage needed to pass. On a smaller level, she expanded the Gang Alternatives Program to all elementary schools in her district. 2010 lieutenant gubernatorial election Hahn ran for Lieutenant Governor of California in 2010 but was defeated in the Democratic primary by San Francisco Mayor Gavin Newsom, finishing second in a field of three candidates. She received 33.3% of the vote against Newsom's 55.5%. U.S. House of Representatives (2011–2016) Elections 2011 On February 7, 2011, Hahn announced her intention to run for the U.S. House of Representatives in the special election to fill California's 36th congressional district seat vacated by U.S. Representative Jane Harman's departure to head the Woodrow Wilson International Center for Scholars. Hahn was one of sixteen candidates from all parties who competed in the special election primary on May 17, 2011. She finished first with 24 percent of the vote; Republican Craig Huey finished second with 22 percent. Because no candidate received more than 50 percent, Hahn and Huey, the top two finishers, faced off in a special runoff election on July 12. Many had expected California Secretary of State Debra Bowen to secure one of the top two spots, but Bowen finished in third place. The Los Angeles County Federation of Labor, AFL–CIO, endorsed Hahn in March 2011, a move the Daily Breeze called "significant" because of the fundraising and get-out-the-vote power of the large organization. As of March 23, 2011, Hahn had received endorsements from Senator Dianne Feinstein, Los Angeles Mayor Antonio Villaraigosa, Los Angeles County Sheriff Lee Baca, California Assembly Speaker John A. Pérez, California State Senator Ted Lieu, Torrance Firefighters Association Local 1138, and other notable figures such as former LA Laker Earvin "Magic" Johnson and environmentalist and actor Ed Begley, Jr. On April 25, 2011, Hahn secured the endorsement of the Los Angeles Times.
