Sen. Coons (D) is running for a third full term. Republican primary: Dr. Mike Katz vs. John Shulli — primary set for September 15, 2026. Delaware is historically Solid Democratic (voted Clinton, Biden, Harris). Coons has missed 3.0% of Senate roll call votes since 2010, slightly above the 2.8% median. His legislative profile focuses on International Affairs (27%), Commerce (21%), and Labor (10%). He holds committee seats on Appropriations (Defense Subcommittee, Ranking Member), Foreign Relations, and Judiciary.
⚡ KATZ CONTRAST POINT: Strategic note for Katz: Coons is well-funded, well-positioned on Delaware funding, and active on national security. Key vulnerabilities: Iran war, DOGE/government spending debate, ICE oversight bill, and any contrast on healthcare policy (Katz's home turf).
