(Reuters) – Former President Donald Trump seeks to show his control over the Republican Party by securing more than 150 endorsements from candidates for November’s midterm elections, which will decide who controls Congress in 2023 and 2024.

Trump will have 12 key choices, some of which are against incumbents members of his party.

The weeks ahead of the primary elections will put Trump’s influence among Republican primary voters. But, Nov. 8 will only show Trump-backed candidates who can win office.

J.D. J.D.

* U.S. Senate seat for Ohio vacated by retiring Senator Rob Portman

* May 3 Republican nomination contest

Vance was backed by Trump. He is perhaps best remembered for his best-seller, “Hillbilly Elegy,” which described the fall of Ohio factory towns to poverty and drug abuse. Though he claims to be an angry populist according to Trumpian standards, recent polls indicate that Vance is in close competition with Josh Mandel, former Ohio treasurer.

TED BUDD

* U.S. Senate seat for North Carolina vacated by retiring Senator Richard Burr

* May 17 Republican nomination contest

Budd, who is a ranking-and-file House of Representatives member, was not well-known in North Carolina before seeking the Republican nomination. It’s expected that the race for November will be close. In public opinion polls, Budd trails Pat McCrory, the former Governor of North Carolina, for most of this race. However, Budd is showing a slight advantage in recent polling.

MEHMET OZ

* U.S. Senate seat for Pennsylvania vacated by retiring Senator Pat Toomey

* May 17 Republican nomination contest

Oz is a well-known celebrity doctor. His public image suffered in 2014 when he stated to lawmakers that he was probing fake diet products ads and said some of his shows’ promoted products were “scientifically questionable.” Trump’s endorsement for Oz split Republican Party leaders in Pennsylvania. A former hedge fund chief David McCormick (NYSE;) and conservative commentator Kathy Barnette are both contenders for Republican Party nomination. Recent public opinion surveys showed that they were nearly tied between the three main candidates. In what will be one of the most competitive races in November’s elections, the winner of the primaries will have to face a Democrat.

HERSCHEL WALKER

* Versus U.S. Senator Raphael Warnock of Georgia

* May 24 Republican primary

Walker is expected to be the Republican nominee. Public opinion polls have already shown that Walker will face Warnock (a Democratic pastor). Trump-endorsed Walker is vulnerable, with past accusations of domestic abuse. Walker supporters are planning to run ads telling Walker that Warnock is too much of a burden.

DAVID PERDUE

* Versus Georgia Governor Brian Kemp

* May 24 Republican primary

Perdue acknowledged that he lost the U.S. Senate election to Jon Ossoff 2021. But in March 2022, he retracted his claim that the election was stolen. He cited evidence that he claimed was fraud, though it was part of a court case that was dismissed by a Judge. Trump’s support for Perdue over Kemp is despite Trump angering Trump’s dismissal of the ex-president’s lies about election fraud. Kemp leads Perdue by a double digit in public opinion polls.

KATIE ARRINGTON

* Versus U.S. Representative Nancy Mace

* June 14 Republican primary for South Carolina’s 1st congressional district

Trump backing Arrington is notable because the South Carolina representative is challenging an incumbent Republican lawmaker, who voted against Trump’s impeachment. Mace protested against Trump shortly after his January 2021 election when she suggested that Congress investigate culping Trump for the role he played in an attack on the U.S. Capitol by his supporters on Jan. 6, 20,21. Arrington is trailing Mace according to public opinion polls.

ROSELL FRY

* Versus U.S. Representative Tom Rice

* June 14 Republican primary for South Carolina’s 7th congressional district

Trump’s choice to unseat Republican Rice is one of few Republicans who voted for impeachment of the ex-leader. He was a Republican state representative with nearly half a million dollars in his campaign on March 31. This suggests a possible race against Rice.

LOREN CULP

* Versus U.S. Representative Dan Newhouse

* Aug. 2 Republican primary for Washington’s 4th congressional district

Trump picked Loren, an ex-small-town chief police officer to challenge Newhouse. Culp had in March demanded the execution of a Black man who is accused of inflicting severe injuries on a woman. Trump had in February endorsed Culp, angry at Newhouse’s vote 2021 for impeachment. Culp had $23,543 while Newhouse had almost $1million in his campaign bank account on March 31.

JOHN GIBBS

* Versus U.S. Representative Peter Meijer

* Aug 2 Republican primary for Michigan’s 3rd congressional district

Gibbs was a Trump-era housing official. His nomination to the U.S. Office of Personnel Management fell after both political parties challenged his tweets that were inflamatory. They also included references to false conspiracy theories and Democrats. Meijer, his opponent who voted against Trump impeachment, leads in fundraising. In what will be one of the most competitive House races this November, the winner in the nomination contest will have to face a Democrat.

JOE KENT

* Versus U.S. Representative Jaime Herrera Beutler

* Aug 2 Republican primary for Washington’s 3rd congressional district

Joe Kent, a former special forces officer, has fought with Matt Gaetz, a far-right U.S. Representative from Florida. He told Oregon Public Broadcasting that he had arranged a conference call on social media with Nicholas Fuentes with the white nationalist Nicholas Fuentes. However Fuentes said he did not agree with Fuentes “ethno nationalism.” Kent’s campaign was in excess of $1 million at the bank as of March 31. This gave him a formidable challenge to Herrera Beutler who voted for impeachment Trump.

KELLY TSHIBAKA

* Versus U.S. Senator Lisa Murkowski of Alaska

* August 16 open primary contest

Trump backs Tshibaka to unseat Murkowski. Murkowski is one of only seven Republican senators to vote to indict Trump on 2021 charges that he had incited rebellion. Trump has made Alaska the focus of his proxy war with Mitch McConnell (Republican Senate Leader), who promised to support Murkowski’s campaign and do all he could to make it a success. Tshibaka had almost $1 million in her campaign bank account on March 31. This suggests she might be a strong opponent.

HARRIET HAGEMAN

* Versus U.S. Representative Liz Cheney

* Aug. 16 Wyoming at-large-district Republican primary

Trump gave his support to Hageman in September 2021 as a land-use attorney, in an effort to penalize Cheney. She was then stripped from her position of No. The former president was impeached on the charge of inciting rebellion. In a December poll, Hageman was ahead of Cheney by 20%.
