District context: The redrawn CA-13 (Prop. 50) spans the northern San Joaquin Valley—Merced, San Joaquin, Stanislaus, Madera & Fresno counties—now including an arm into Stockton. The 2024 race was the closest House race in the nation, decided by 187 votes. The redrawn map is considered more favorable to Democrats than the prior lines. Race rating: Competitive / Lean Democratic (post-redistricting). CA-13 is a priority target for both the DCCC and NRCC.

Advantages
  • Incumbent with proven district delivery—bipartisan water, farm bill, and infrastructure wins in first term
  • Prop. 50 redistricting added more Democrats to CA-13—new map considered more favorable to Gray
  • Fundraising lead—Gray holds more cash on hand heading into the general per FEC filings
  • DCCC full institutional support: staff, data, air support, voter contact
  • California Farm Bureau endorsement signals crossover appeal with Republican-leaning farmers
  • Moderate “Blue Dog” brand suits swing district; does not threaten conservatives on guns, water, or ag
  • Deep roots and three previous campaigns in the district—name recognition advantage
  • Trump personal endorsement activates national MAGA donor and volunteer networks
  • NRCC “MAGA Majority” program provides national GOP infrastructure and ad spending
  • Executive experience as mayor of Stockton—California’s 11th largest city
  • Marine Corps veteran background resonates with military-heavy Valley communities
  • Stockton now inside redrawn CA-13—Lincoln is a known local figure there
  • Came within 2.4 points of winning CA-9 in 2024—proven competitive general election candidate
  • Unique biography (Black/Latino Marine veteran pastor) complicates Democratic attack lines
  • Speaker Johnson endorsement adds House leadership prestige and fundraising contacts
Vulnerabilities
  • Razor-thin 2024 win (187 votes) signals persistent competitiveness—no margin for error
  • Three consecutive close races show structural drag; district is not safe Blue territory
  • Foreign policy positions (pro-Israel, AIPAC-linked) risk voter discontent among Arab American and progressive communities
  • Co-sponsored Gottheimer Iran resolution—voted against Khanna-Massie war powers effort—exposed as insufficiently anti-war for activists
  • Missed vote rate (5.3%) higher than median congressional member—potential contrast target
  • Blue Dog brand may depress progressive base turnout if enthusiasm lags
  • Republican midterm environment could stall expected Democratic structural gains
  • Lost CA-9 in 2024—this is his second consecutive congressional race attempt; label as a repeat loser
  • Redrawn CA-13 favors Democrats—Prop. 50 added more Democratic voters intentionally
  • Strong Trump alignment may be a liability in a competitive general (Trump lost CA broadly)
  • Not a district native in the same way Gray is—Stockton-centric identity vs. Merced-centered district core
  • Platform lacks detailed agricultural policy—a weakness in the nation’s most productive farmland
  • Anti-midterm wave environment for GOP: national mood expected to disadvantage Republicans in 2026
  • Gray has legislatively delivered on water and ag—Lincoln must overcome a record of tangible constituent results
Campaign & Major Donors
  • 2024 cycle total expenditures: ~$3.15M (OpenSecrets); fundraising heavily again for 2026

  • JDCA-affiliated Jewish donor network
  • New Democrat Coalition PAC and Blue Dog PAC affiliated support
  • Labor unions and local business associations across the five-county district
  • FEC data shows Lincoln fundraising and spending heavily; trails Gray in cash on hand

  • San Joaquin County business and real estate donor base from mayoral networks
  • Former Rep. John Duarte donor contacts—inherited when Duarte endorsed Lincoln
  • National Republican dark money and party infrastructure expected to activate
Foreign Policy
  • Voted against the Khanna-Massie bipartisan War Powers Resolution to end U.S. involvement in the Iran war
  • Co-sponsored the Gottheimer alternative Iran resolution (H.Con.Res. 75)—a more moderate, pro-Israel alternative that set a March 30 deadline for the conflict
  • Statement on Iran: “The Constitution is clear—Congress carries the solemn responsibility to declare war. The President must present a clear strategy… before the U.S. is drawn further into another conflict.”
