5 Key Races to Watch in Tuesday’s US Primaries

The Democratic Party faces a critical test of its ideological divide during primary elections in Michigan, Kansas, Missouri, Virginia, and Washington state, according to reporting by Reuters. In Michigan, a state won by Donald Trump in 2024 where Democrats need a net gain of four seats to retake the Senate, progressive candidate Abdul El-Sayed is challenging center-left U.S. Representative Haley Stevens for the Democratic U.S. Senate nomination.

The Michigan Senate Primary: Progressives Face Establishment Pushback

Michigan’s Senate race highlights a fierce internal contest between party wings. Abdul El-Sayed, a former unsuccessful candidate for governor, has secured endorsements from prominent progressives including U.S. Senators Bernie Sanders and Elizabeth Warren, according to Reuters. Meanwhile, U.S. Representative Haley Stevens enters the primary backed by the Democratic establishment, including Michigan Governor Gretchen Whitmer. Stevens has also benefited from tens of millions of dollars in outside spending by a pro-Israel super PAC, as reported by Reuters. Recent primary polls show El-Sayed leading Stevens by double digits, though general election surveys suggest Stevens may present a stronger matchup against former U.S. Representative Mike Rogers, the 2024 Republican Senate nominee running unopposed who holds $4.5 million in his campaign war chest.

Divided Moderates in Lansing-Area House District

The progressive-moderate friction extends down-ballot to a Lansing-area congressional district currently represented by Republican Tom Barrett. According to Reuters, the three-way Democratic primary features two moderates—former U.S. Navy SEAL Matt Maasdam and former U.S. Ambassador to Ukraine Bridget Brink—alongside progressive climate activist William Lawrence. Establishment Democrats have expressed concern that Maasdam and Brink could split the center-left vote, potentially opening a path to victory for Lawrence in a district that Donald Trump won by 1.3 percentage points in 2024.

Cori Bush Seeks Comeback in Missouri Rematch

In Missouri, former U.S. Representative Cori Bush is mounting a comeback bid in a primary rematch against U.S. Representative Wesley Bell, according to Reuters. Bush, a progressive and vocal critic of Israel, lost her seat last cycle after a pro-Israel super PAC spent $8 million to unseat her. That same organization, the United Democracy Project, has deployed more than $3 million this cycle to block her return to Congress. The winner of the safe Democratic, St. Louis-area district is heavily favored in November.

Shri Thanedar Faces Detroit-Area Primary Challenger

U.S. Representative Shri Thanedar faces a two-man primary race in his Detroit-area district against Donavan McKinney, a Black state representative, according to Reuters. Thanedar is endorsed by House Minority Leader Hakeem Jeffries, while McKinney has secured backing from several progressive lawmakers, including Sanders and U.S. Representative Rashida Tlaib, as well as members of the Congressional Black Caucus. While McKinney has raised more than $1.3 million, Thanedar can draw on substantial personal wealth for his campaign. Black residents comprise roughly 45% of the district’s population.

Kansas Supreme Court Reform Referendum

Voters in Kansas are deciding on a constitutional referendum that could alter how state Supreme Court justices are chosen, according to Reuters. Justices are currently selected through a process where the governor picks from three finalists chosen by a nine-member commission. The proposed amendment would replace this system with popular elections for six-year terms, rolling out between 2028 and 2032. Kansas Attorney General Kris Kobach acknowledged in 2022 that popular elections for the bench could allow the state to slowly restrict abortion access following the state Supreme Court’s 2019 and 2024 rulings protecting abortion rights under the state constitution.
