Combat Veteran Wins Nevada House Primary, Playing to Trump’s Base

A decorated Air Force combat veteran who lined up support from the Trump wing of the Republican Party will face a Democratic incumbent in a tossup congressional race in Nevada.

The Republican candidate, Sam Peters, won a three-way primary in Nevada’s Fourth District. The seat has been held by Steven Horsford, a Democrat, for the past two terms as well as a single term a decade ago.

Mr. Peters, 47, defeated Annie Black, The Associated Press said Wednesday. Ms. Black is an assemblywoman who attended the Jan. 6, 2021, rally for Mr. Trump in Washington and was censured by state lawmakers for refusing to wear a mask. Chance Bonaventura, a Republican campaign operative who is chief of staff for a Las Vegas city councilwoman, finished third in Tuesday’s primary.

Since the Fourth District’s creation a decade ago, Republicans have won the seat just once, holding it for a single term. The party is seeking to seize upon the sagging approval numbers of President Biden and lingering attention on the personal issues of Mr. Horsford, who has acknowledged having an extramarital affair.
