CA-13 is rated Toss-up / Lean R. Duarte's 8-point win in 2024 was a significant improvement over his 564-vote squeaker in 2022, reflecting real Republican gains with Central Valley Latino voters. However, the district remains on the Democratic target list, and a strong enough national environment combined with the right Democratic candidate could make this competitive again.

The Candidates
John Duarte
Farmer and nursery owner from the Modesto area. Survived the closest House race in the country in 2022 (564 votes, 0.4%). Ran on agricultural issues and water rights. Won more comfortably in 2024 with an ~8-point margin, benefiting from Trump's improved performance with Latino voters. His agricultural background gives him authentic credibility with the district's farming communities.
Weaknesses: Still a competitive district; Democratic fundraising advantage in California; tariff exposure on agricultural exports.
Central Valley Democrat
Democrats will need to recruit a candidate who can speak credibly to agricultural and working-class Latino concerns — ideally someone from the Merced, Modesto, or Stockton area with community roots. Adam Gray came within 564 votes in 2022 but lost by 8 points in 2024. Democrats need a fresh profile to reset the race dynamics in this shifted electorate.
Challenges: Latino voter trend toward Republicans; Duarte has built genuine agricultural credibility.

District Election History
Race Analysis
The District: California's Agricultural Heartland and the Latino Realignment
California's 13th congressional district is the agricultural heart of America — a flat, intensely farmed expanse of the Central Valley where almonds, walnuts, tomatoes, dairy herds, and dozens of other commodities grow at industrial scale. The cities of Modesto, Merced, and the Stockton suburbs are processing and logistics hubs for this agricultural economy. The district is majority Latino, with large communities of Mexican-American families across multiple generations, plus newer immigrant communities tied to agricultural labor.
The political story of CA-13 over the past decade has been the most dramatic Latino realignment of any California district. In 2020, under a prior district configuration, the Democratic predecessor held the seat by 15 points. In 2022, under new lines, Duarte won by 564 votes — an outcome that shocked both parties. In 2024, Duarte expanded to an 8-point win as Trump's outperformance with Latino voters nationally was reflected acutely in the Central Valley. Working-class Latino communities in this district have responded to Republican messaging on immigration enforcement, economic security, and cultural conservatism in ways that have redrawn the political map.
The key variable heading into 2026 is whether this realignment is durable or whether aggressive immigration enforcement, tariff impacts on agricultural exports, and economic hardship for farm labor communities create a backlash. Central Valley farmers depend on federal water allocations perpetually contested in California water politics — an issue where Duarte has credibility as an actual farmer but where any federal water policy changes could either help or hurt him. Agricultural tariffs are a direct economic threat: Central Valley crops are heavily export-dependent, and any trade war impacts on commodity prices will be felt immediately by growers and workers alike.
Key Issues
Water Rights & California Water Politics
Water allocation is existential for Central Valley farmers. The federal Central Valley Project and the State Water Project supply irrigation water that makes large-scale agriculture possible in what is naturally a semi-arid climate. Any changes to water contracts, environmental flows, or drought policy directly affect livelihoods. Duarte, as an actual farmer, has deep credibility here, but federal water policy decisions could still create winners and losers in the district.
Agricultural Tariffs & Export Markets
Central Valley crops — almonds, pistachios, walnuts, tomatoes — are heavily export-dependent. China, Europe, and other markets absorb a large share of production. Any trade war that triggers retaliatory tariffs on US agricultural exports hits CA-13 farmers directly and immediately. This is a potential wedge issue for Democrats against an incumbent Republican whose party controls trade policy.
Immigration Enforcement & Farm Labor
The immigration paradox of CA-13: Central Valley agriculture depends on immigrant labor — documented and undocumented — to harvest crops, yet many working-class Latino voters in the district support stronger immigration enforcement. Aggressive deportation policies could simultaneously remove farm laborers that growers need and appeal to established Latino voters who feel economically threatened by labor competition. Duarte must navigate this tension carefully.
What to Watch in 2026
- Tariff impacts on agricultural exports: If Trump administration tariffs trigger retaliatory tariffs from China or the EU on Central Valley commodities (almonds, walnuts, tomatoes), the economic pain in CA-13 is direct and immediate. Watch commodity prices and export data through 2025-2026.
- Immigration enforcement effects on farm labor: Aggressive deportation programs could remove agricultural workers that Central Valley farms depend on. If labor shortages drive up costs or leave crops unharvested, economic impact could generate political backlash against Republicans even among voters who supported enforcement in the abstract.
- Latino voter trend durability: The 2024 shift of Latino voters toward Republicans in the Central Valley was dramatic. Watch whether it consolidates, reverses, or plateaus. Local election results and polling in the region will provide early signals.
- Democratic candidate recruitment: Democrats need a fresh face after Adam Gray's 2022 near-win turned into a 2024 blowout. The quality of Democratic recruitment will determine whether this race is genuinely competitive or fades from the target list.
- Water policy decisions: Any federal water allocation decisions affecting the Central Valley Project will be covered intensely locally. Duarte's ability to deliver on water rights will be tested during the 2025-2026 legislative cycle.

The dominant issues are California water rights and allocation (existential for farmers), agricultural tariffs and export markets, immigration enforcement and farm labor supply, and California gas prices. Water policy is the defining local issue; trade policy is the major national wildcard.
What was notable about the 2022 CA-13 race?
