Illinois voters will select a successor to retiring Democratic Sen. Dick Durbin in the November 2026 general election. The Democratic primary concluded in March with Lt. Gov. Juliana Stratton securing the nomination after defeating Reps. Raja Krishnamoorthi and Robin Kelly, aided by endorsements and spending from Gov. JB Pritzker. Republicans nominated former state party chair Don Tracy. Illinois has not elected a Republican to the Senate since 2010, and nonpartisan race ratings classify the contest as safe or solidly Democratic. These structural factors, combined with the state's consistent partisan voting patterns in recent cycles, underpin trader consensus assigning overwhelming probability to the Democratic nominee. A national Republican surge, unforeseen candidate controversy, or unusually low Democratic turnout could still shift dynamics before Election Day.
