Chris Coons Leads Delaware Democratic Senate Primary

Voters in Delaware cast ballots on Tuesday, September 15, 2026, in primary elections for the U.S. Senate, U.S. House, and several statewide offices. Chris Coons, the incumbent Democratic U.S. Senator, is heavily favored to win his primary and secure a path toward a third full term. Coons entered the race with endorsements from Governor Matt Meyer and U.S. Senator Lisa Blunt Rochester, though he faced challenges from Jeff Appelhans, Mary Louve, and another candidate.

The primary became a focal point for intra-party tension regarding foreign policy. Appelhans and Louve campaigned on ending or questioning U.S. military support for Israel, specifically criticizing Coons for opposing resolutions to ban the sale of military equipment and bulldozers to the Israeli government. Despite these progressive challenges, Coons maintained strong support from establishment Democrats and the American Israel Public Affairs Committee.

Other key contests included the Democratic primary for Attorney General, where incumbent Kathy Jennings faced challengers, and the Republican primary for U.S. Senate featuring Michael Katz and John Shulli. While primary turnout in Delaware is historically low, early and absentee voting increased this year, with over 38,500 ballots cast prior to election day, surpassing 2024 figures.
