WASHINGTON (Reuters] – On May 10, the Republican-leaning US states of Nebraska, West Virginia and South Dakota will hold primaries for U.S. House of Representatives seats and other office offices.

These are some notable races that may influence the November 8 midterm elections, when Republicans seek to take control of Congress.

WEST VIRGINIA 2ND CONGRESSIONAL DITRICT

Two incumbent Republican U.S. Representatives could face another challenge due to former President Donald Trump’s endorsements. According to polls, there is an extremely close race between Alex Mooney (backed by Trump) and David McKinley (endorsed by Jim Justice of West Virginia).

Because West Virginia’s House seats are shrinking, the incumbents will be facing each other. Because the district is overwhelmingly Republican, the winner of the contest for the nomination will probably win in November.

NEBRASKA GOVERNORSHIP

Trump’s endorsement will face another challenge in Nebraska’s Republican primary for governor. Charles Herbster (who Trump backed) was recently accused of touching several women. Herbster is a farmer executive who has denied these allegations.

Recent public opinion polls have not been conducted by independent pollsters but have shown that there is a possible competitive race between Herbster (the former Republican governor) and University of Nebraska Regent Jim Pillen (who has been endorsed both by the Farm Bureau as well as the Farm Bureau).

Republicans are expected to win the November election.

NEBRASKA 2ND CONGRESSIONAL DISTRICT

The district’s center is Omaha, which is the largest city in the state. Republican Don Bacon has held the 2nd congressional district since 2017.

Although Bacon will not face any stiff competition internally in May, Alisha Shelton and Tony Vargas are the Democratic Party primaries. Vargas has proclaimed his support for assault rifle bans, while Shelton pledged to improve voting access.
