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. Coons has missed 3.0% of Senate roll call votes since 2010. His legislative profile focuses on International Affairs (27%), Commerce (21%), and Labor (10%). Committees: Appropriations (Defense Subcommittee Ranking Member), Foreign Relations, Judiciary. No new public polling has emerged this week, but Coons's campaign has been actively fundraising off DOGE opposition messaging and healthcare themes — areas where he may perceive vulnerability to Katz's physician background.
⚡ KATZ CONTRAST POINT: Strategic note for Katz: Coons is well-funded and active on national security. Key vulnerabilities this cycle: DOGE/government spending reform debate (Katz has actual restructuring legislation to cite), ICE oversight bill (Katz's border security platform), healthcare policy (Katz's home turf as a physician with 40+ years' experience), and government transparency (Katz's lobby reform bill SB 141, live-streaming bill SR 14, and term limits bill SB 61 from the Delaware Senate all demonstrate a reform record Coons cannot match after 15 years of incumbency). Katz should continue building name ID downstate and among independents who are frustrated with cost of living — per his homeownership and economy platforms.
