Delaware's 2026 Senate race tests a long-standing Democratic stronghold against a former party member.
In short: On November 3, 2026, Delaware voters will decide the future of a Senate seat held by Democrats for over three decades. Incumbent Chris Coons seeks a third full term, facing a challenge from Michael Katz, a former Democratic state senator who secured the Republican nomination in a decisive primary victory.
The 2026 election cycle in Delaware highlights a significant political trend, as the state has remained a reliable Democratic stronghold in Senate contests since 1994. Chris Coons, who has served in the U.S. Senate since 2010, entered this race with the backing of his party, securing the Democratic nomination on September 15 with 78% of the vote. His campaign focuses on maintaining this long-standing dominance in a state that has not elected a Republican senator in over thirty years.
Challenging the incumbent is Michael Katz, a figure with a unique political trajectory. Katz previously served as a Democratic state senator from 2009 to 2013 and was the Independent Party nominee for the U.S. Senate in 2024. His shift to the Republican ticket marks a notable transition; he successfully clinched the Republican nomination with 77.3% of the vote. He defeated John Shulli, an instructor at the U.S. Army War College, to earn his spot on the general election ballot.
While the race features other figures such as businessman Eric No-Trump Hansen, who previously ran for the Senate in 2024, the primary contest between Coons and Katz remains the central narrative. The outcome on November 3 will determine whether the Republican party can finally break its multi-decade losing streak in Delaware or if the incumbent will successfully secure his third full term in office. The dynamics of this race reflect broader shifts in political allegiances and the enduring influence of incumbency in Delaware politics.
