Democrats face a significant challenge in Michigan's Senate primary, with U.S. Rep. Haley Stevens competing against progressive Abdul El-Sayed. The tight race, still unresolved early Wednesday, tests the party's willingness to move away from moderate candidates. Winning this seat is crucial for Democrats to regain control of the Senate. Meanwhile, Republicans chose their nominee for Michigan governor, going with Trump-endorsed John James over wealthy outsider Perry Johnson. The American Israel Public Affairs Committee is trying to remain influential, spending heavily in Michigan to support Stevens. In Virginia, Democrats aim to recover seats after a failed redistricting effort. Primaries in other states will shape November's matchups.

U.S. Rep. Wesley Bell has won a rematch in a Missouri Democratic primary against former Rep. Cori Bush, an outspoken activist who had been part of a progressive group of House members known as the Squad. Bell’s primary victory Tuesday is likely to propel him to reelection in November in the heavily Democratic 1st Congressional District in St. Louis. Bell was backed by a political group affiliated with the American Israel Public Affairs Committee. The pro-Israeli group also financed his ouster of Bush in the 2024 primary. The contest between Bell and Bush, who received support from democratic socialists, tested how much the Democratic Party has shifted over the past two years.

Missouri’s top election official has rejected a petition for a statewide referendum on new congressional districts backed by President Donald Trump. Supporters submitted hundreds of thousands of signatures to try to force a November election on a new U.S. House map approved by the Republican-led state Legislature. But Republican Secretary of State Denny Hoskins asserted Tuesday that the petition is unconstitutional because congressional redistricting plans cannot be subject to voter referendums. A group backing the referendum effort plans to challenge Hoskins’ decision in court. Missouri was the second Republican-led state, after Texas, to respond to Trump’s call to redraw congressional districts to the GOP’s advantage.

The Republican leader of the Indiana Senate is giving up his position after six GOP incumbents who opposed President Donald Trump on his congressional redistricting push in the state lost their primaries. Indiana Senate President Pro Tem Rodric Bray drew the ire of Trump in December when he voted against the redistricting plan after saying for weeks that it didn’t have enough support to pass. Bray announced Friday that he would not seek reelection to the post when Senate Republicans choose their leaders in November. His current Senate term runs through 2028 and he will remain in office, albeit not in a leadership position.
