In a closely watched race, Democrat Adam Gray defeated Republican incumbent John Duarte by under 200 votes in California's 13th District, marking an important Democratic pick-up. This victory shifts the balance in the U.S. House to Republicans holding 220 seats against Democrats’ 215, but raises potential challenges for GOP majority due to upcoming vacancies. Gray's campaign centered on water management and agriculture, contrasting with Duarte's focus on inflation. Despite boosting their seats, Democrats face turnout issues and setbacks in the state Legislature, indicating the need for renewed focus on crime and cost of living concerns.
