California is the most populous state in the country, which means it has the most electoral votes to give. With 55 electoral votes at stake, winning the Democratic stronghold's popular vote can put a candidate almost a fifth of the way to winning the 270 electoral votes required to win the election. The last Republican candidate to win the state was former President George H.W. Bush. Former Secretary of State Hillary Clinton won the state by 30 points in 2016.
