Juan Vargas is running against No declared opponents yet (filing deadline March 6, 2026).
Vargas represents the only congressional district spanning the entire California-Mexico border, home to the San Ysidro Port of Entry -- the busiest land border crossing in the Western Hemisphere (70,000 vehicle passengers and 20,000 pedestrians daily). In the Trump era, his seat is a critical frontline for immigration policy and border community advocacy. The district has a Cook PVI of D+13, making it safely Democratic, but his voice on deported veterans and immigration reform gives the seat outsized national importance.
Won 2024 reelection with 66.3% over Justin Lee (R). Introduced the Deported Veterans Bill Package (I-VETS Act, HOPE Act, NATS Act) to prevent veteran deportations. Authored the Emergency Tribal Housing Assistance Act signed into law as part of American Rescue Plan ($750M). District includes San Diego, Chula Vista, National City, Otay Mesa, and all of Imperial County. Ran for Congress four times before winning in 2012 after predecessor vacated for mayoral bid.
Key dates to watch: Primary on June 2, 2026 and General Election on November 3, 2026.
