Political Science Professor Elizabeth Bergman is becoming the Bay Area expert on the Tea Party. In addition to KTVU, she was also interviewed by CBS5 News for "Pleasanton Mom Behind Major Tea Party Rally."
"It would be prudent for politicians to tap into it," said Bergman. "It's an audience that's able to express a poplar, populist sentiment."
