DOWNEY - Luis Marquez, mayor of Downey and a senior aide to state Sen. Alan Lowenthal of Long Beach, confirmed today that he will run for the California State Assembly in the newly-created 58th District.Marquez, who was elected to the City Council in 2008, said he will formally announce his intentions tomorrow. Recently redrawn by the state's redistricting commission, the new assembly district, which includes the cities of Montebello, Cerritos, Downey, Commerce, Bell Gardens, Pico Rivera, Bellflower, and Artesia, is quickly becoming treasured territory for local politicians. While Assemblyman Ricardo Lara of Bell Gardens has yet to announce whether he will seek reelection in the new district, other hopefuls are already eyeing the vacant assembly seat including former state assembly member Tom Calderon, brother of state Sen. Ron Calderon and Assemblyman Charles Calderon, who announced in August his intentions to run in the new district. This will not be Marquez's first attempt to run for state office. In 2010, Marquez campaigned against Lara in the 50th Assembly District for the democratic nomination, but ultimately came in third behind South Gate City Clerk Carmen Avalos. Marquez said he will issue a statement tomorrow explaining his decision to run for the assembly seat.
