U.S. House of Representatives District 25 Primary
This election for a seat covering parts of Los Angeles County and Ventura County fills the vacancy left by former Democratic U.S. Rep. Katie Hill, who resigned in October. If a candidate receives more than 50% of the vote, they will be automatically elected and the runoff election will be cancelled. Otherwise the top two finishers in the primary advance to a runoff election on May 12, 2020. The winner of the special election will finish the remaining balance of Hill’s term. A separate primary will determine which two candidates will compete in November to fill the full two-year term starting in 2021.
