LANCASTER, CA – OCTOBER 21: Democratic congressional candidate Katie Hill (CA-25), C, dances at a campaign Halloween carnival event on October 21, 2018 in Lancaster, California. Hill is competing for the seat against Republican incumbent Rep. Steve Knight. Democrats are targeting seven congressional seats in California, currently held by Republicans, where Hillary Clinton won in the 2016 presidential election. These districts have become the centerpiece of their strategy to flip the House and represent nearly one-third of the 23 seats needed for the Democrats to take control of the chamber in the November 6 mid term elections.
