South Dakota Governor Kristi Noem, a staunch ally of former President Donald Trump who is known for her opposition to COVID-19 restrictions, won the Republican nomination to seek reelection in November, as voters cast ballots in primary elections across seven U.S. states.

Edison Research projected that Noem defeated former state House speaker Steven Haugaard 75.3% to 24.7%. Noem ran for reelection after ignoring Trump's urging for her to challenge Republican Senator John Thune.

Noem has been mentioned as a possible vice presidential running-mate if Trump seeks election again in 2024 or as a White House candidate in her own right if he does not.

Thune also won the party nod, despite drawing Trump's ire by criticizing objections to the 2020 presidential election.

New Jersey Republican Tom Kean Jr. won his party's nomination to challenge embattled Democratic Representative Tom Malinowski in November, as voters cast ballots in primary elections across seven U.S. states, according to Edison Research..

Kean, the son of popular two-time Governor Thomas Kean, had nearly 52% of the vote, far ahead any of his field of rivals. Malinowski, who is viewed as one of the most vulnerable Democrats in the country, also secured his renomination.

Polls also closed in Iowa, Mississippi, New Mexico and Montana but remained open in California, where voters cast ballots in nominating contests that will set the competitive field for Nov. 8's elections, which will determine control of Congress for the next two years.

With President Joe Biden slumping in the polls and soaring inflation souring voters' moods, Republicans are expected to win control of the House of Representatives and possibly the Senate, which would bring Biden's legislative agenda to a halt and give Republicans the power to launch distracting and possibly politically damaging investigations.

Just 41% of Americans approve of Biden's performance as president, near the lowest level of his presidency, according to a Reuters/Ipsos public opinion poll completed on Tuesday.

The poll also showed the Democratic Party and the Republican party were neck-and-neck in voter preferences ahead of the November congressional elections. Thirty-nine percent said they would vote for a Democrat compared to 37% picking a Republican. The difference was well within the poll's 4 percentage point credibility interval.

In Montana, Ryan Zinke, who served as interior secretary under Republican former President Trump, is running for a newly created House seat that the state gained thanks to population growth and the once-a-decade redistricting process.

Zinke, who served in Congress previously, faces four Republican challengers, some of whom claim that he is too liberal or lacks commitment to the state because his wife's residence is in California.

Zinke was accused in an inspector general report this year of using his position as head of the Interior Department to advance a development project in his hometown and lying to an ethics investigator. He has denied wrongdoing.

CALIFORNIA SHAKEOUT

A pair of races in California also illustrate liberal-leaning voters' frustrations with spikes in homicides and gun violence.

Polls show that San Francisco's progressive district attorney, Chesa Boudin, is likely to be pushed out of office in a recall vote. A replacement would be chosen by the city's mayor, London Breed, a Democrat who has criticized Boudin but has not taken a stance on the recall.

In Los Angeles, Rick Caruso, a billionaire developer and former Republican, is battling U.S. Representative Karen Bass and a host of other liberal candidates in the mayoral election.

Caruso, who has spent more than $30 million of his own money in the campaign, made crime the centerpiece of his candidacy in a city that saw homicides reach a 15-year high in 2021. That forced Bass, a longtime progressive champion in Congress, to move to the center and pledge to put more police on the streets. Caruso and Bass could be headed to a runoff, polls show.

In Iowa, former state Senator Zach Nunn outpaced two other Republicans to seize the party nomination to challenge embattled Democratic Representative Cindy Axne.

Nunn, the only Republican contender who has held elective office, boasts a string of endorsements from high-profile party luminaries including Trump's former Secretary of State Mike Pompeo and several sitting House Republicans.
