Lead

Voters across six US states went to the polls on Tuesday in primary elections that will set the stage for November's midterm contests, where control of Congress is at stake. With all 435 seats in the House of Representatives and roughly a third of the Senate on the ballot, Democrats are hoping to win majorities in both chambers and take back power from Republicans.

The busiest primary day of the season saw voting in California, Montana, New Jersey, New Mexico, South Dakota, and Iowa, with candidates for at least 74 House seats selected to advance to the general election.

Coverage

Reporting on Tuesday's contests highlighted several races that could shape the balance of power in Washington. Al Jazeera's overview noted that the outcomes could influence the political landscape for the remainder of President Donald Trump's second term, with control over Congress at stake in November.

The Guardian's coverage emphasized Democratic hopes of flipping key districts, pointing to New Jersey's Rebecca Bennett as a challenger who could oust Republican incumbent Tom Kean Jr. In Iowa, the paper reported, Democrats believe they can be competitive in three of the state's four House races as well as the open Senate seat left by retiring Republican Senator Joni Ernst. The paper also noted that California's redrawn maps could give Democrats an advantage in several contests.

Key races and results

In Iowa's Democratic Senate primary, state representative Josh Turek won the nomination, defeating state senator Zach Wahls. Turek benefited from millions of dollars in outside spending, including from the PAC VoteVets, which has previously received contributions from Senate Minority Leader Chuck Schumer's campaign fund. Wahls had positioned himself as an outsider willing to challenge party leadership, arguing that Turek was the establishment's preferred candidate. Turek countered that he was more electable, having won office in a conservative-leaning district. He will face Republican Representative Ashley Hinson, whom former President Donald Trump has endorsed for the seat.

In New Jersey, Democrat Rebecca Bennett is running against Republican incumbent Tom Kean Jr. in a race that Democrats see as a potential pickup.

The primary format varies by state. In California, for example, most statewide primary races are nonpartisan, with the top two vote-getters from any party advancing to the November ballot.

Perspectives

The Democratic primary in Iowa's Senate race offered voters a clear choice between two visions for the party. Turek's campaign emphasized electability, citing his previous victory in a conservative-leaning district as proof that he could compete in the general election. Wahls, by contrast, ran on a platform of challenging party insiders, specifically criticizing Schumer for what he called a weakening of the party's message. The contest became contentious, with Wahls accusing outside groups of trying to install his opponent, while Turek's supporters argued that his record of winning in difficult territory made him the stronger candidate for November.

The general election races ahead will test whether Democrats can translate their primary success into midterm gains. In Iowa, the party is hoping to be competitive in races where Republicans have dominated for the past decade, while in New Jersey the focus is on whether Bennett can unseat Kean in a district that has become more competitive in recent cycles.

What was claimed, and who backed it

Each row is one claim, attributed to the outlet whose wording states it most clearly. Confidence rates how directly the source text states the claim — explicit and unhedged rates high; hedged, pieced-together, or internally inconsistent statements rate lower. It does not measure whether the claim is true. Status counts the distinct outlets we found asserting it — so a single-source claim can still show high confidence, and a multi-source claim can show medium. Every one of those outlets is named beside the status, so you can check the count against the list. For claims extracted before we began storing that list, the row says so: it names the outlet the claim is quoted from and states that we have not recorded which outlets backed it. Outlets wrote at different times, so a figure that evolves — a casualty count, for example — can legitimately differ between rows; check the "as of" time next to each claim's source.
