The owner of half a dozen legal brothels in Nevada has a slim lead with about two-thirds of the votes counted in a Republican race for a legislative seat.

A state election official and a member of The Associated Press election tabulation team say an unspecified technical issue delayed the count of votes for more than two hours in a rural northern Nevada county.
The vote tally glitch in Pershing County came late Tuesday, hours after election officials reported "isolated' early problems with some of the state's new touch-screen voting machines in Washoe and Clark counties, including the Reno and Las Vegas areas.
Nevada Secretary of State's office spokeswoman Jennifer Russell says officials know of no cases where voters were unable to successfully cast ballots.
Russell and AP election team member Alicia Craig in Lovelock say Pershing County votes began downloading for counting about 9:30 p.m.

Voters picked two candidates for a November runoff to replace one retiring Nevada Supreme Court justice.
Clark County District Court Judge Elissa Cadish and State Court of Appeals Judge Jerry Tao were the top vote-getters Tuesday among five candidates seeking to succeed retiring Justice Michael Cherry.
They topped Carson City attorney John Rutledge, Lyon County District Judge Leon Aberasturi and Las Vegas lawyer Alan Lefebvre.
The November ballot also will offer a choice between current Justice Lidia Stiglich and Clark County Family Court Judge Mathew Harter. They did not face a primary because they were the only two candidates to seek the seat.
Nevada Court of Appeals Judge Abbi Silver will replace retiring Justice Michael Douglas on the seven-member state high court in January, after she drew no primary challenger.

Danny Tarkanian has won the Republican primary for Nevada's 3rd District congressional seat left open by the incumbent Democrat who's running against GOP Sen. Dean Heller in November.
The son of former UNLV basketball coach Jerry Tarkanian will face Las Vegas Democrat Susie Lee in the high stakes battle that is expected to be the most expensive congressional race in Nevada this fall.
Lee clinched the Democratic nomination Tuesday. Both candidates raised well over $1 million in their primary campaigns.
Tarkanian didn't enter the House race until March when President Donald Trump and others persuaded him to abandon an aggressive bid to knock off Heller in the Senate primary.
The incumbent congresswoman, Jacky Rosen, won the Democratic Senate nomination Tuesday for the right to challenge Heller in November.

Sisolak outraised and outspent Giunchigliani in the race and earned backing from former Nevada Democratic Sen. Harry Reid.
He's expected to face Republican state Treasurer Adam Laxalt in the November election.
Sisolak has spent a decade on the governing body for Clark County, which includes the Las Vegas Strip and about two-thirds of the state's residents.

Conine was an executive at the Golden Nugget casino-hotel in Las Vegas and an investment analyst before co-founding the business consulting firm Joseph Beare & Co.
Beers cites a background as a certified public accountant. He served in the state Senate from 1999 to 2008, lost primary bid for governor in 2006 and was elected to the city council in 2012. He lost a re-election bid in 2017.

Hardy, a former state legislator, unseated then-Democratic Rep. Steven Horsford in the 2014 general election.
Horsford won the nomination in the Democratic primary Tuesday night, setting up a rematch in November in the swing district that stretches from north of Las Vegas through four rural counties.

Horsford, the first African American elected to Congress in Nevada, faced five other opponents in the Democratic primary, including state Sen. Patricia Spearman.

U.S. Rep. Mark Amodei has defeated conservative activist Sharron Angle and won the Republican Party's nomination as he seeks re-election to Nevada's 2nd Congressional District.

Amodei is expected to win re-election in November to the Republican-heavy district.
He was first elected in 2011 to replace Dean Heller, who had been appointed to the U.S. Senate.
Angle is a former legislator who gained national attention in 2010 when she unsuccessfully challenged ex-Senate Majority Leader Harry Reid. She also lost a 2016 bid to become the GOP's nominee to replace Reid.

Democrat Steven Horsford has won the Democratic primary for the 4th District congressional seat he held in southern Nevada for one term before Republican Cresent Hardy defeated him in 2014.

Incumbent Democratic Rep. Ruben Kihuen announced earlier this year he would not seek re-election to a second term amid allegations of sexual misconduct.

Democrat Susie Lee cruised to an easy primary victory in a key congressional race in Nevada, setting up a battle in November for the seat left open when U.S. Rep. Jacky Rosen decided to run for Senate.
Lee captured the Democratic nomination against largely unknown rivals Tuesday night in the 3rd District covering much of suburban Las Vegas.
The wealthy Las Vegas philanthropist, who has an endorsement from Vice President Joe Biden and financial backing from several national abortion rights groups, is expected to face Republican Danny Tarkanian in November.

U.S. Rep. Dina Titus has easily locked up the Democratic nomination as she runs for re-election in Nevada's 1st Congressional District.
The congresswoman on Tuesday defeated challenger Reuben D'Silva.
Titus is a former University of Nevada, Las Vegas professor and former state legislator who was first elected in 2012.
D'Silva is a high school teacher and former Marine who was awarded the Purple Heart after he was injured in Iraq in 2007.
Titus's Las Vegas district includes the Las Vegas Strip and surrounding neighborhoods. It leans Democratic and her re-election in November is considered a safe bet.
7:56 p.m.
Nevada Republican Dean Heller has secured his party's nomination as he seeks re-election to the U.S. Senate.
Heller defeated four others in the Republican primary on Tuesday. He was able to cruise through his primary race after President Donald Trump earlier this year persuaded Heller's main challenger, Danny Tarkanian, to drop out. Tarkanian sought a U.S. House seat, instead.
Heller is considered the most vulnerable Republican U.S. senator seeking re-election this year because he's the only one running in a state that Democrat Hillary Clinton won in 2016.
Heller was a past critic of the president but has become closer to him in recent months and helped deliver the overhaul of the U.S. tax codes to Trump's desk in December.
7:58 p.m.
U.S. Rep. Jacky Rosen has become the Democratic Party's nominee to take on Republican U.S. Sen. Dean Heller in November.
Primary election results Tuesday show Rosen sailed past five lesser-known Democrats.
Rosen is a former computer programmer, software designer and president of a Henderson synagogue who narrowly won her House seat in 2016 after being recruited to run by former Democratic Sen. Harry Reid.
She has portrayed Heller as a flip-flopper who has cozied up to President Donald Trump.

Paul Laxalt and son of former U.S. Sen. Pete Domenici of New Mexico.
He supported Donald Trump for president in 2016.
He's backed in his bid for governor by billionaire casino owner Sheldon Adelson and Americans for Prosperity, a conservative advocacy group funded by the wealthy Koch brothers.
Moderate Republican Gov. Brian Sandoval is leaving the office because he is term-limited.

Results are upcoming in dozens of legislative and primary races in Nevada now that polls have closed.
The most closely watched race Tuesday is the gubernatorial primary race in which Clark County Commission colleagues Steve Sisolak and Christina Giunchigliani are vying to be the state's first Democratic governor in two decades.
Nevada Deputy Secretary of State for Elections Wayne Thorley has said voters were turning out in higher rates than past primary elections because of the close primary race to succeed outgoing Gov. Brian Sandoval in November.
Republican U.S. Sen. Dean Heller is expected to breeze through the primary race after President Donald Trump earlier persuaded his strongest GOP opponent to drop out.
