OAKLAND (KRON) — Hillary Clinton is campaigning in the Bay Area on Friday ahead of California’s primary on June 7.

Clinton is scheduled to be in Oakland at the La Escuelita Elementary School at 2 p.m. Then she will head over to San Francisco for a fundraising event.

Residents should be aware of possible traffic congestion due to crowds of not only supporters but also protestors.

Thursday night hundreds of protestors showed up to Clinton’s event in Los Angeles. A similar scene is expected in the Bay Area.

Clinton’s campaign has not released the location for the event in San Francisco.

Clinton plans to discuss her plans to “raise incomes for families and break down the barriers that hold Californians back,” according to her campaign officials.

Until recently, the California primary had looked like the make-or-break contest for candidates on both sides of the aisle. But billionaire businessman Donald Trump is now the presumptive Republican nominee, while Bernie Sanders looks to California as his last glimmer of hope in stopping Clinton, who has thus far won 92 percent of the delegates needed to claim the nomination.

But Clinton can’t be too confident going in to the country’s final primary, with statewide voter surveys pointing to a tight race between the two Democrats.

An independent Field Poll released last month found Clinton with a 6-point lead over Sanders, with 12 percent of voters still undecided.

The California election is actually about a month long.

Vote-by-mail ballots go out next week and could account for more than half of the total number of votes cast. That means that many voters will be making decisions weeks before June 7.

In California, 475 Democratic delegates will be divvied up in the election, some based on the outcome in each congressional district, others in proportion to the statewide tally. That will make it difficult for either candidate to win a commanding victory.The Associated Press contributed to this report
