In the 2024 House race for CA-12, Lateefah Simon (D) defeated Jennifer Tran (D) 65.4% to 34.6%. Lateefah Simon received 185,176 votes compared to 97,849 for Jennifer Tran, a dominant 30.9-point margin reflecting a safely partisan district.
This was an open-seat race with no incumbent running — Barbara Lee (D) previously held the seat. Open seats typically attract stronger candidates and heavier spending from both parties. The 2024 presidential election drove higher voter turnout, which can help or hurt down-ballot candidates depending on the top of the ticket. The wide margin suggests this district is firmly in the Democrat column for the foreseeable future.
