SAN FRANCISCO (KGO) -- California's primary is just one day away and Hillary Clinton and Bernie Sanders are making final pushes in the Bay Area.The final push for votes finds Democratic candidate Bernie Sanders with his biggest campaign event: A concert at Crissy Field in San Francisco.Hours before Sanders was expected to take the stage, the crowd began arriving."I think he's going to take it. I think it's going to wake up the Democrat party," San Francisco resident Roger Crawfod said.Sanders told supporters it comes down to them. "If there is a large voter turnout we will win," Sanders said."He wants to get money out of politics, which is the only thing that'll shape our nation into what we need it to be," George Davison said.Leah Palmer came in from the Lake County town of Kelseyville. "I'm for Bernie Sanders because of income equality, women's rights, education and a living wage," she said.Sanders says he won't concede to rival Hillary Clinton even if she takes California on Tuesday. His supporters aren't ready to give in either."Anything can happen between now and November. He's not as far behind as people want you to think," said one Sanders supporter.Sanders was on a whirlwind tour of the Bay Area. He started with a news conference in Emeryville and went on to give a speech at San Francisco City College. Then surprised supporters with impromptu stops in Chinatown and the Haight-Asbury neighborhood before his rally at Crissy Field.The Crissy Field campaign event, "A Future To Believe In," featured a concert headlined by the Dave Matthews Band and other musicians, such as Norwood Fisher, with the L.A. group Fishbone and a dedicated backer of the Vermont senator. "It's an honor to be a part of this because no matter what, he's changed the course of the future," Fisher said.
