The Republican party was founded in 1854 to oppose the introduction of slavery into the newest states to enter the union, including California. The California Republican Party came into existence at a convention held at a Congregational Church in Sacramento (the location is now Macys store at the Westfield Shoppingtown Downtown Plaza). The history of the national Republican Party has had a strong ties to California. The first Republican candidate for President, John C. Fremont, had served as one of California's first US Senators and two of the last five Republicans elected to the presidency were Californians; Reagan and Nixon. In recent years, as the voters of California moved to the left, the number of Republicans elected to statewide office gradually declined until after the 2002 Gubernatorial election, when Democrats gained control of all nine of the statewide offices. Republicans managed to regain the office of Governor (2003-2011), Secretary of State (2005-2007) and Insurance Commissioner (2007-2011), the Republicans again lost all the statewide offices in the 2010 and 2014 Gubernatorial elections.
The "15 Day Report of Registration" for the 2018 Statewide Direct Primary Election (May 28, 2018) was the first in which No Party Preference voters outnumbered Republicans. As of late May 2018, California voters are 25.07% Republican and 25.51% No Party Preference.
