Adam Laxalt won the Republican nomination Tuesday for a pivotal Nevada Senate seat, fending off a challenge from a political newcomer and setting up a fierce November contest to topple incumbent Democrat Catherine Cortez Masto in a race that could swing power in the U.S. Senate.

In Republican-dominated Nye County, the political mudslinging came to a fever pitch ahead of Tuesday’s June 14 primary election, where there was fierce competition in the GOP race for District 4 county commissioner between incumbent Leo Blundo and one of his two challengers, businessman Ron Boskovich.

Right-wing Republican candidates won a majority of statewide races in the Nevada primary Tuesday, many of whom have embraced election conspiracies. But that doesn’t mean that a red wave is coming in November, some experts say.

Adam Laxalt is one of Nevada's most prominent Republicans, someone who has already won statewide office and attracted support from both former President Donald Trump and Senate Republican leader Mitch McConnell.

One television ad proclaims this candidate will keep Nevada safe and get the state “back on track.” At the end of the advertisement, there is notice saying the message is not from the candidate, but an outside group not affiliated with the candidate.

The U.S. Supreme Court appears poised to overturn Roe v. Wade this summer with a ruling that would erode federal protections for abortion rights established nearly 50 years ago, refueling the polarizing debate in many of Nevada’s most competitive races.
