Of the roughly 200 candidates endorsed by former President Donald J. Trump in the 2022 midterm elections, many are running unopposed or face little-known, poorly funded opponents. But in contested races, those endorsed by Mr. Trump have won more times than they have lost.
Mr. Trump’s endorsement has helped propel some candidates to victory, like J.D. Vance in Ohio and Bo Hines in North Carolina. His picks also won critical primaries in Pennsylvania and West Virginia. But in Georgia, several of his candidates were resoundingly defeated, and he had mixed success in states like South Carolina and North Carolina.
Here is a look at his endorsement record in some of the most closely watched primaries.
In Georgia, several losses, and one victory
Gov. Brian Kemp easily defeated former Senator David Perdue, Mr. Trump’s handpicked candidate, in the Republican primary for governor. Mr. Kemp was a Trump target after he refused to overturn the president’s re-election loss there in 2020. He will face the Democratic nominee, Stacey Abrams, whom he narrowly defeated four years ago.
Secretary of State Brad Raffensperger, who refused Mr. Trump’s demand that he “find” additional votes after his 2020 loss, defeated a Trump-backed challenger, Representative Jody Hice, in the Republican primary.
In the Republican primary for an open seat in Georgia’s Sixth Congressional District, the Trump-backed candidate, Jake Evans, qualified for the June 21 runoff, though he was a distant second to the top vote-getter, Rich McCormick.
The former professional football star Herschel Walker, who was endorsed by Mr. Trump, dominated the Republican primary for Senate. He will face Senator Raphael Warnock, a Democrat and prolific fund-raiser, in the general election.
Doug Mastriano, a state senator and retired Army colonel who has propagated myriad false claims about the 2020 election and attended the protest leading up to the Capitol riot, won the Republican nomination for governor. Mr. Trump endorsed him just a few days before the May 17 primary.
But Representative Madison Cawthorn crumbled under the weight of repeated scandals and blunders. He was ousted in his May 17 primary, a stinging rejection of a Trump-endorsed candidate. Voters chose Chuck Edwards, a state senator.
A split in South Carolina House races
Representative Tom Rice, one of 10 House Republicans who voted to impeach Mr. Trump after the Jan. 6, 2021, attack on the Capitol, was ousted by his Trump-backed challenger, State Representative Russell Fry, in the Republican primary in the Seventh Congressional District.
But Representative Nancy Macedefeated her Trump-backed challenger, the former state lawmaker Katie Arrington, in the First Congressional District primary. Ms. Mace had said that Mr. Trump bore responsibility for the Jan. 6 attack, but she did not vote to impeach him. She had support from Nikki Haley and Mick Mulvaney, who both held office in the state before working in the Trump administration.
Why are these midterm races so important? This year’s races could tip the balance of power in Congress to Republicans, hobbling President Biden’s agenda for the second half of his term. They will also test former President Donald J. Trump’s role as a G.O.P. kingmaker. Here’s what to know:
What are the midterm elections? Midterms take place two years after a presidential election, at the midpoint of a presidential term — hence the name. This year, a lot of seats are up for grabs, including all 435 House seats, 35 of the 100 Senate seats and 36 of 50 governorships.
What do the midterms mean for Biden? With slim majorities in Congress, Democrats have struggled to pass Mr. Biden’s agenda. Republican control of the House or Senate would make the president’s legislative goals a near-impossibility.
What are the races to watch? Only a handful of seats will determine if Democrats maintain control of the House over Republicans, and a single state could shift power in the 50-50 Senate. Here are 10 races to watch in the House and Senate, as well as several key governor’s contests.
When are the key races taking place? The primary gauntlet is already underway. Closely watched races in Pennsylvania, North Carolina and Georgia were held in May, with more taking place through the summer. Primaries run until September before the general election on Nov. 8.

Victories in Ohio
The Senate candidate J.D. Vancedefeated a field of well-funded candidates, nearly all of whom pitched themselves as Trump-like Republicans. Mr. Vance, an author and venture capitalist, had transformed himself from a self-described “never Trump guy” in 2016 to an “America First” candidate in 2022.
Max Miller, a former Trump aide who denied assault allegations from an ex-girlfriend and was later endorsed by Mr. Trump, won his House primary after two other Republican incumbents there opted not to run.
Mr. Trump also endorsed Madison Gesiotto Gilbert, a lawyer and former beauty queen who had been a surrogate for his presidential campaign. She won a seven-way primary for an open congressional seat being vacated by Representative Tim Ryan, a Democrat running for Senate.
Kevin Kiley, a Republican state lawmaker endorsed by Mr. Trump, advanced to the November general election after his second-place finish in an open primary for an open seat in California’s Third Congressional District. He will face Kermit Jones, a Democrat who is a doctor and Navy veteran and was the top vote-getter.
A narrow win in Montana
Ryan Zinke had been Montana’s at-large congressman before serving in the Trump administration. Now Mr. Zinke is looking to return to Congress. Mr. Trump endorsed him, but he only narrowly won his Republican primary for the seat.
A loss in Nebraska
Charles W. Herbster, a wealthy agribusiness executive, lost his three-way primary to Jim Pillen, a University of Nebraska regent who was supported by Gov. Pete Ricketts, who had long clashed with Mr. Trump and is term-limited. Late in the campaign, Mr. Herbster was accused of groping several women. He denied the accusations.
And another loss in Idaho
Gov. Brad Little of Idaho overcame Mr. Trump’s endorsement of the state’s lieutenant governor, Janice McGeachin, who was challenging him in the Republican primary.
