⚡ KATZ CONTRAST POINT: Strategic note for Katz: Coons is well-funded and active on national security. Key vulnerabilities this cycle: the DOGE/government spending debate where Katz's restructuring record provides credibility; ICE/immigration enforcement where Coons is out of step with Delaware's moderate swing voters; healthcare policy where Katz's 40+ years as a physician and his DHIN innovation record are powerful differentiators; and government transparency where Katz authored lobby reform (SB 141), term limits (SB 61), live streaming (SR 14), and redistricting transparency (SR 9) legislation in Dover. Katz should continue building name ID downstate and among veterans communities near Dover AFB.
