CALIFORNIA RAZOR-THIN DISTRICTS 2026
The Narrowest Margins: California’s 2026 Battleground
California holds two of the closest House races in 2024, both now vulnerable Democratic freshmen in 2026. Adam Gray in CA-13 won by 187 votes — the narrowest House race in the nation. Derek Tran in CA-45 won by 613 votes, beating Michelle Steel to become Orange County’s first Vietnamese American representative. Together, these two districts represent the absolute thinnest Democratic margins in the House and the most direct electoral test of PAC money’s impact per dollar spent.
In both districts, Republicans are heavily favored to rematch or mount strong challenges. Agricultural PAC money in CA-13, combined with traditional Republican super PAC spending, will compete directly against Democratic effort to defend these seats. In CA-45, Michelle Steel has already declared her candidacy for a rematch, guaranteeing one of the most expensive House races in 2026.
CA-13: Adam Gray’s 187-Vote Margin
District Profile
Location: Central Valley (parts of Stanislaus, Merced, Kern, Kings, and Tulare counties)
Demographics: Agricultural heartland; high concentrations of farmworkers, agribusiness interests, and food processing workers
Performance: 2024: Adam Gray (D) defeated incumbent Rep. John Duarte (R) by 187 votes out of 200,000+ cast — the closest House race in the nation. California’s 13th Congressional District election, 2026 - Ballotpedia (Tier 3)
Cook Partisan Index: R+1 (Republican-leaning, but won by Democrat in 2024)
Why Gray is Vulnerable
Gray’s 2024 victory was one of the most stunning upsets of the cycle. He flipped a traditionally Republican seat by fewer than 200 votes. His hold on the district is extremely tenuous.
Republican challenger: Former Stockton Mayor Kevin Lincoln has filed for the Republican nomination, positioning himself as the establishment Republican challenger. Lincoln will likely face other Republicans in a primary before facing Gray in the general election. Kevin Lincoln launches Congressional campaign for District 13 - ABC10 (Tier 3)
Historical context: Gray’s ability to flip this seat came from split-ticket voting and candidate-specific factors. Without John Duarte’s weaknesses, a traditional Republican should be favored in a district coded R+1.
Money
Gray won CA-13 by 187 votes. In 2026, spending is expected to exceed $30-50M in this district alone. A House Majority PAC investment of $2-3M per point of swing would easily determine the outcome. Republican agricultural PAC money targeting California crops and pesticide policy will add additional pressure on Gray.
Republican Super PAC Strategy
Republicans will deploy the Congressional Leadership Fund and Americans for Prosperity Action in CA-13 to protect and flip the seat back. This district is on the National Republican Congressional Committee’s offensive target list as a prime pickup opportunity.
The agriculture lobby has direct financial interest in CA-13 outcomes. Farm Bureau PACs, pesticide manufacturers, and water management groups will coordinate spending with Republican candidates.
2026 Rematch Dynamics
Gray’s 2024 win came despite the district’s Republican lean. Replicating that win requires:
- Repeating the 2024 candidate quality advantage (Duarte had ethical problems)
- Outspending Republicans in TV/digital advertising
- Holding agricultural workers despite anti-immigration messaging
All three are in jeopardy in 2026.
CA-45: Derek Tran vs. Michelle Steel — Orange County’s Asian American Representation Under Siege
District Profile
Location: Orange County (parts of Garden Grove, Westminster, Santa Ana, Fountain Valley, and Huntington Park)
Demographics: Historically Republican, strong Asian American community (Little Saigon), large immigrant population
Performance: 2024: Derek Tran (D) defeated incumbent Rep. Michelle Steel (R) by 613 votes. Tran became the first Vietnamese American to represent Little Saigon in Congress. Derek Tran defeats Michelle Steel in California’s 45th congressional district - Orange County Register (Tier 2)
Cook Partisan Index: D+1 (Democratic-leaning by 1 point, first time Orange County district favors Democrats at presidential level)
The Rematch
Michelle Steel has already declared her candidacy to run again in 2026, guaranteeing an immediate rematch. California’s 45th Congressional District election, 2026 - Ballotpedia (Tier 3)
This is unprecedented: the two closest House races in 2024 are now locked into 2026 rematches, both in California, both with vulnerable incumbents elected by fewer than 700 votes combined.
Contradiction
Michelle Steel’s 2024 loss broke a Republican hold on Little Saigon that had lasted decades. Steel represented Orange County’s Vietnamese American community for four years. Yet she lost to Tran, also Vietnamese American, suggesting the election turned on something other than ethnic representation — likely anti-incumbent sentiment and Trump’s unpopularity in immigrant communities in November 2024.
In 2026, the presidential context will be different. Trump is president. Immigration enforcement is a central issue. Steel will emphasize law-and-order framing. Tran will fight to hold suburban, college-educated voters and Asian American support.
Historical Significance
Derek Tran’s election was culturally significant: the first Vietnamese American to represent Orange County’s Vietnamese community in Congress. Tran broke a ceiling. In 2026, Steel will attempt to reclaim the seat, testing whether Tran’s thin 2024 coalition can hold.

Projected 2026 Spending
Both CA-13 and CA-45 are expected to be among the most expensive House races nationally in 2026. Projections:
CA-13 (Gray):
- Candidate committees: $2-3M each
- House Majority PAC: $8-15M for Gray
- Congressional Leadership Fund / AFP: $8-15M against Gray
- Other PACs: $5-10M
- Total projected spending: $25-50M+
CA-45 (Tran):
- Candidate committees: $2-3M each
- House Majority PAC: $5-12M for Tran
- Congressional Leadership Fund / AFP: $5-12M for Steel
- Issue PACs (Asian American groups, labor, environmental): $5-10M
- Total projected spending: $20-40M+
Class Analysis: Agricultural vs. Labor Money in CA-13; Immigrant Economic Power in CA-45
These two races reveal competing donor structures in California House politics:
CA-13 (Gray): This is where agricultural PAC money competes directly with labor union and environmental group spending. Gray’s 2024 coalition combined agricultural workers’ interest with environmental voters opposing agribusiness consolidation. In 2026, the farm lobby’s spending will test whether that coalition holds.
CA-45 (Tran): This is an Asian American immigrant economic power battle. Vietnamese American business communities in Little Saigon have direct economic interests in trade policy, immigration, and tax code. Tran’s victory proved Vietnamese American voters could swing Republican-coded districts. Steel will attempt to reclaim that vote by framing Tran as insufficiently tough on crime/immigration.
Both races pit narrow margins against massive spending. The 2026 cycle will demonstrate whether House races this close are determined by local politics or by super PAC resources.
