OMAHA, Neb. (AP) — The top race in Tuesday’s primary elections in Nebraska is a heavily contested Republican primary for Nebraska governor, featuring a Donald Trump-endorsed candidate who has been accused of groping multiple women.

Voters in Nebraska will also be nominating candidates to replace former U.S. Rep. Jeff Fortenberry, a Republican convicted in March on charges he lied to federal authorities about an illegal campaign contribution he received from a Nigerian billionaire.

What to watch as Tuesday’s primaries unfold:

HOW MUCH SWAY DOES TRUMP HAVE IN NEBRASKA?

In Nebraska’s Republican primary for governor, Trump has endorsed Charles Herbster, a wealthy agribusinessman and cattle breeder who has positioned himself as a political outsider.

Herbster has recently faced allegations that he groped young women, including a Nebraska state senator and a former legislative staffer. He vehemently denies the accusations and has filed a defamation lawsuit against the lawmaker, state Sen. Julie Slama. She filed a countersuit, accusing Herbster of sexual battery. Despite the allegations, Trump has stood by Herbster and appeared with him at a rally last week.

His main rival is University of Nebraska regent Jim Pillen, a former college football player and veterinarian who owns a hog farm operation and swine breeding-stock company. Pillen has won support from high-profile conservatives, including Gov. Pete Ricketts, former Gov. Kay Orr, the influential Nebraska Farm Bureau and former Nebraska football coach Tom Osborne.

And in a surprising twist, state Sen. Brett Lindstrom of Omaha has risen to top-tier status as well with support from Omaha’s Republican mayor and ads in which he pitches himself as a “new generation” of leader. He is considered the more moderate option to Herbster and Pillen.

The winner of the GOP primary is expected to face state Sen. Carol Blood, who is all but certain to win the Democratic nomination for governor over a little-known candidate who hasn’t actively campaigned.

HOW DID A CONGRESSMAN’S CONVICTION RESHAPE THE PRIMARY?

U.S. House primary races are usually low-key affairs in Nebraska, with little turnover among the Republican incumbents. But the state has an open seat this year following Fortenberry’s resignation.

Fortenberry initially planned to seek reelection to a 10th term despite a federal indictment and launched attack ads against his main challenger, Republican state Sen. Mike Flood. He dropped his bid after his conviction, and Flood gained momentum with endorsements from Ricketts and former Gov. Dave Heineman.

Flood is now the strong favorite to win the nomination for the 1st Congressional District out of a field of five Republican candidates. Fortenberry’s name will still appear on the ballot because he withdrew after the state’s deadline to certify candidates.

The GOP nominee is expected to face Democratic state Sen. Patty Pansing Brooks in November. Pansing Brooks is running against University of Nebraska-Lincoln student Jazari Kual Zakaria in the Democratic primary.

Flood and Pansing Brooks will also face each other in a June 28 special election to decide who serves the rest of Fortenberry’s term. The November general election will determine who fills the seat starting in January 2023.

The 1st Congressional District encompasses a stretch of eastern Nebraska, excluding Omaha and most of its suburbs. The Republican-leaning district includes Lincoln as well as large stretches of farmland and small towns.
