Assemblyman Rich Gordon, D-Menlo Park, announced Thursday morning that he would seek a second term in Sacramento.

Gordon represents the 21st District, which will include Mountain View and Sunnyvale this year, thanks to the recent redistricting.

Gordon, a veteran San Mateo County supervisor who was elected to the state Assembly in 2010, touted in his announcement his success during his freshman term. Of the 19 bills he proposed, 15 were signed into law by Gov. Jerry Brown, including proposals to extend tax exemptions to public land trusts and to exempt volunteers from prevailing-wage requirements for public-works projects.

He was also one of the architects, along with state Sen. Joe Simitian and U.S. Rep. Anna Eshoo, of a proposal to blend Caltrain and high-speed rail on the Peninsula -- a proposal that the California High-Speed Rail Authority largely endorsed in its latest business plan.

As chair of the Assembly's Budget Subcommittee on Resources and Transportation, he has been heavily involved in reviewing the latest plans for the controversial rail line. He also serves on the Budget, Health, Local Government, Joint Sunset Review and Revenue and Taxation committees and is a member of the Environmental and LGBT caucuses.

"Over the last year, it has been an honor to represent the residents of the Peninsula," Gordon said in a statement. "I am proud of what we have accomplished, in particular on issues regarding the environment and government efficiency. Yet there is still much more work to be done."

Gordon's reelection campaign has already received endorsements from a host of state and federal officials, including Eshoo, Simitian, Santa Clara County Supervisors Liz Kniss and Ken Yeager, Palo Alto Mayor Yiaway Yeh and all five members of the San Mateo County Board of Supervisors.
