Voters are going to the polls in five states, including Michigan, where Democrats are watching the expensive and contentious Senate primary contest between populist Abdul El-Sayed and moderate Rep. Haley Stevens.They're running for retiring Democratic Sen. Gary Peters' seat, which is among a handful that Democrats must hold in order to have any chance of winning control of the Senate. Gov. Gretchen Whitmer is backing Stevens, while Sen. Bernie Sanders and Rep. Alexandria Ocasio-Cortez are campaigning for El-Sayed. Former GOP Rep. Mike Rogers, who lost to Sen. Elissa Slotkin by less than a point in 2024, is running unopposed in the Republican primary.

Democrats are still targeting several districts in their fight for control of the House.In Missouri, ongoing redistricting legal battles may yet affect congressional races, where longtime Democratic Rep. Emanuel Cleaver's district has been redrawn to favor the GOP and five Republicans are vying for the chance to take him on in November. In the only reliably Democratic district in the state, the 1st, Democratic Rep. Wesley Bell is being challenged by former Rep. Cori Bush, whom he defeated two years ago. In Kansas, Democratic Gov. Laura Kelly's tenure will be ended by term limits, opening up the governor's race in the reliably GOP state. There are also primaries in Washington, where the top-two vote getters, regardless of party, will advance to the general election. Four Democrats and three Republicans are vying to take on two-term Rep. Marie Gluesenkamp Perez, who is a frontrunner to make the ballot in the 3rd District this fall. And in the Seattle area, longtime Rep. Adam Smith is being challenged by former Seattle City Council member Kshama Sawant, a socialist, along with several others.
