San Diego Developer Aaron Feldman and employees of his Sunroad group of companies currently enmeshed in the Montgomery Field office-tower dustup have long bankrolled many local GOP candidates and their causes, including ex-mayor Susan Golding and current mayor Jerry Sanders. Last October 11, for instance, Sunroad Asset Management, Inc., gave $10,000 to the mayor's San Diegans for City Hall Reform political committee, which campaigned for two successful ballot propositions that give Sanders greatly expanded control of city government, including the ability to "outsource" city services to private providers. In recent years, Feldman and his workers have also given generously to Republican congressmen Darrell Issa, Brian Bilbray, and John Campbell. But sometimes Feldman gets out his checkbook for Democrats, too. During last year's bitter Democratic primary battle between Congressman Bob Filner and termed-out assemblyman Juan Vargas, Feldman gave to both. This year, Feldman is back securely in the Filner camp, so much so that he was listed as a "host" of a lavish political fund-raiser Filner threw for himself at the Mission Bay Hilton on April 12. Other hosts listed on the invitation to the event, entitled "Celebrating the New Direction for America," included Luce, Forward lawyer Charlie Bird, developer Michael Gelfand, shopping-center owner Elliot Feuerstein, and lobbyist Lynne Heidel, as well as the American Occupational Therapy PAC. "Chairs" for the evening were the American Dental Association PAC & San Diego Dental Society and the National Electrical Contractors Association PAC. ... The number-one zip code in California for contributions to Emily's List, the liberal political action committee, is currently La Jolla.

Donors included longtime Democratic moneyman Murray Galinson and attorney Claudette G. Wilson. The number-one state was California, with total contributions of $138,735. Total individual contributions were $645,161.
