Barr has won the presidential nomination of the Peace and Freedom Party.
Her vice presidential running mate is Bay Area activist Cindy Sheehan. She is the mother of a soldier killed in Iraq and anti-war activist best known for her protest outside of then-President George W. Bush's Crawford, Texas, ranch.
As of now, Barr will not appear on enough ballots in November to have a mathematical chance of winning the White House or having much of an effect on the final outcome.
The Peace and Freedom Party, based in California, historically has had little ballot presence outside the state.
