OMAHA, Neb. (AP) — Nebraska Republicans will pick a nominee for governor Tuesday in a bitter primary race that was upended in recent weeks after a leading candidate endorsed by former President Donald Trump was accused of groping at least eight women over the last few years.

Charles Herbster, a businessman and cattle breeder who has denied the allegations, is in a nine-way GOP primary to replace Republican Gov. Pete Ricketts, who’s prevented by term limit laws from running again. Other leading candidates include Jim Pillen, a veterinarian and hog farm owner endorsed by Ricketts, and state Sen. Brett Lindstrom, an Omaha financial adviser who gained traction recently with a surge of money and support from the city’s Republican mayor.

The winner will emerge as a strong favorite in November’s general election in Republican-dominated Nebraska. State Sen. Carol Blood is the top candidate for the Democratic nomination for governor. Polls close at 9 p.m. Eastern time.

Both Nebraska and West Virginia are holding primary elections Tuesday, with select races providing some measure of the former president’s enduring sway with GOP voters. In addition to the Nebraska governor’s race, Trump has weighed in on a West Virginia congressional primary between two Republican incumbents. The former president backed Rep. Alex Mooney over Rep. David McKinley, who angered Trump by voting for President Joe Biden’s bipartisan infrastructure package and the creation of the House committee investigating the Jan. 6 attack on the Capitol.

Trump is facing some of the biggest tests of his influence in Republican primary elections later this month. In Pennsylvania, his endorsed Senate candidate, TV’s Dr. Mehmet Oz, is locked in a competitive race against former hedge fund CEO David McCormick and five others, while his candidate in North Carolina, U.S. Rep. Ted Budd, is competing in a field that includes a dozen other Republicans. In Georgia, Trump has endorsed primary challengers to Gov. Brian Kemp and Secretary of State Brad Raffensperger, both of whom defied him by rejecting his false claims of voter fraud in the 2020 election.

In Nebraska, the allegations against Herbster, a longtime supporter of Trump’s, didn’t stop the former president from holding a rally with him earlier this month.

“I really think he’s going to do just a fantastic job, and if I didn’t feel that, I wouldn’t be here,” Trump said at the rally at a racetrack outside Omaha.

In a story last month, the Nebraska Examiner interviewed six women who claimed Herbster had groped their buttocks, outside of their clothes, during political events or beauty pageants. A seventh woman said Herbster once cornered her privately and kissed her forcibly.

One of the accusers, Republican state Sen. Julie Slama, said Herbster reached up her skirt and touched her inappropriately at the Douglas County Republican Party’s annual Elephant Remembers dinner in 2019. The Associated Press does not typically identify people who say they are victims of sexual assault unless they choose to come forward publicly, as Slama has done.

Herbster filed a defamation lawsuit against Slama, saying she falsely accused him in an effort to derail his campaign. Slama responded with a countersuit against Herbster, alleging sexual battery.

Herbster has suggested in television ads that Pillen and Ricketts conspired with Slama to falsely accuse him of sexual assault — allegations the three deny.

Some voters said the allegations didn’t dissuade them from backing Herbster.

As she voted at an elementary school in northwest Omaha on Tuesday, Joann Kotan said she was “upset by the stories, but I don’t know if I believe them.” Ultimately, the 74-year-old said she voted for Herbster “because President Trump recommended him.”

Lindstrom has faced a barrage of attacks as well, with third-party television ads funded by Ricketts that portray him as too liberal for the conservative state. One digitally altered ad shows Lindstrom standing in front of a rainbow flag with a coronavirus mask superimposed over his face. A mail ad notes that Lindstrom was endorsed by U.S. Rep. Brad Ashford, a moderate Republican-turned-Democrat who died last month of brain cancer.

But Devon Leesley said he backed the 41-year-old Lindstrom because “it’s time to hand over the politics to the next generation.” Pillen and Herbster are both in their 60s.

The 45-year-old Leesley, who lives in Omaha, said he didn’t pay much attention to the various endorsements in the race.

“I don’t trust any politician talking about any other politician. It’s all dirt,” he said. “We would never vote for anybody if we listened to their opponent.”

Carol Bruning, 59, of Omaha, said she went into Election Day debating between Pillen and Lindstrom, but went with Pillen because of his age and experience. She said she liked that Ricketts but that former football coach and congressman Tom Osborne endorsed Pillen. The fact that Trump endorsed Herbster may have even been a little bit of a turnoff at this point, even though Bruning said she voted for Trump.

The allegations against Herbster weren’t much of a factor.

“You don’t know what to believe. That’s the hard part,” Bruning said.

Nebraska Secretary of State Bob Evnen, a Republican, predicted that 35% of registered voters will cast ballots in the primary, the highest percentage since 2006, based on what he’s seen so far.
