U.S. President Barack Obama (L) attends a campaign fund raiser for Democratic Senator Barbara Boxer (R) in Los Angeles, California in this October 22, 2010 file photograph. With Obama still fairly popular in the state despite the beating his approval rating has taken elsewhere, Democrats say turning out the young California voters who helped him win in 2008 election is essential to carrying the midterm U.S. Senate and governor's races.
