Delaware's 2026 U.S. Senate race features incumbent Democrat Chris Coons seeking a fourth term against Republican Michael Katz, following both candidates' primary victories on September 15. Trader consensus heavily favors the Democrat at 98.6 percent due to the state's consistent Democratic voting patterns in federal contests, Coons' established record since 2010, and nonpartisan forecasts rating the contest solid or safe Democratic with double-digit polling margins. Republicans have not won a Senate seat here since 1994. Factors sustaining the gap include limited opposition funding and no major shifts in voter sentiment since primaries. Scenarios that could narrow the outcome remain narrow, such as an unforeseen late scandal, health development affecting the incumbent, or an exceptional national political realignment before November 3.
