Honda’s new television ad hit the airwaves this week, hitting Khanna as the tool of the “billionaires, right-wing activists (and) corporate interests” who the incumbent says are funding his campaign. Khanna, a 38-year-old Silicon Valley attorney, has spent millions on TV ads and mailers attacking the 73-year-old Honda as a politician of the past, a do-nothing congressman who needs to make way for someone better attuned to the needs of the high-tech industry in the 17th Congressional District, which includes Fremont, Santa Clara, Cupertino, Sunnyvale and part of San Jose. “I don’t think there’s anyone — Democrat, Republican or decline to state — who wants a congressman who refuses to reach across partisan lines and who isn’t willing to put his constituents ahead of party politics,” said Tyler Law, a spokesman for Khanna. Honda’s new ad features little more than “guilt by association,” said Law, by spotlighting Khanna donors like PayPal co-founder Peter Thiel, who has given $2 million to the Republican-oriented Club for Growth, and Marc Leder, a supporter of Republicans, including 2012 presidential candidate Mitt Romney and Florida Sen.
