SACRAMENTO, Calif. (AP) — California is the largest prize in the calculations of any Democratic presidential candidate, and Bernie Sanders has been working the state for months, worrying his rivals. Sanders has been organizing intensively among Latinos and young voters, producing campaign materials in seven languages, going, as one aide said, “where most candidates don't go.” Mike Bloomberg has tried to counter Sanders with saturation advertising, including buying time at television stations in Arizona, Nevada and Oregon that also reach California.
