SOUTH SAN FRANCISCO, Calif. (KCBS) _ Senator Barbara Boxer brought her re-election campaign to South San Francisco on Tuesday, visiting Solazyme, a small company that makes oil for everything from engines to cookie out of algae.

“You are on the cutting edge of change and innovation,” she said. “I’m so proud of you.”

Senator Boxer saluted Solazyme, which has benefited from several federal grants and contracts.

Boxer used her visit to highlight her support for the “green economy” and opposition to Proposition 23, which her Republican opponent, Carly Fiorina, supports.

But a new Rasmussen Poll says Firoina has surged ahead of Boxer, whose five-point lead just two weeks ago is now a one-point deficit.

Boxer said she remains confident that her message will carry the day.

“While I’m fighting for jobs in America, she doesn’t care about American jobs,” Boxer said. “She shipped them overseas, she’s opposing every single jobs bill and I think those are the issues that resonate.”

Fiorina said Boxer hasn’t made good on her past promises to create jobs and Prop 23 will suspend what she calls a “job killing” law.
