Nevada Gov. Joe Lombardo will face six Republican challengers in a state primary on Tuesday, while state Attorney General Aaron Ford, Washoe County Commissioner Alexis Hill and four others will compete for the Democratic nomination to reclaim the seat in November. Other races on the ballot include primaries for U.S. House and a variety of state offices, as well as a mayoral election in Henderson, the state’s second largest city. All three of Nevada's Democratic U.S. representatives are seeking reelection, while the delegation's lone Republican is retiring.
