The expected vote is the total number of votes that are expected in a given race once all votes are counted. This number is an estimate and is based on several different factors, including information on the number of votes cast early as well as information provided to our vote reporters on Election Day from county election officials. The figure can change as NBC News gathers new information.

LAS VEGAS (AP) — Nevadans are choosing their party nominees Tuesday for two closely watched congressional seats and the governor’s race, among others, as the state grapples with an affordable housing shortage, exploding energy demand from data centers and federal cuts to key state programs.

The state has a closed primary, meaning only registered Democrats and Republicans will vote in party contests after an effort to open them up failed in 2024.

Several primaries feature matchups between candidates backed by party leaders and political outsiders promising change. Come November, the governor’s race is considered one of the most competitive in the country, and holding on to the 3rd Congressional District is considered crucial for Democrats’ hope of retaking the U.S. House.

Here’s a look at the most prominent races:

Democrats seek a rival for Lombardo

Gov. Joe Lombardo, a Republican, is considered one of the most vulnerable governors in the country this fall.

The Democrats vying to challenge him include state Attorney General Aaron Ford, who has the backing of the Democratic congressional delegation and former Vice President Kamala Harris, and Alexis Hill, a county commissioner in northern Nevada who campaigned as a candidate willing to shake things up.

They focused their campaigns on affordability, as the state continues to see a shortage of affordable housing, some of the highest gas prices in the country and cuts to federal healthcare and food assistance programs.

Ford largely ignored Hill, instead directing his attacks at Lombardo and arguing that both the governor and Trump are responsible for Nevadans’ economic woes. He is trying to become Nevada’s first Black governor.

2nd Congressional District

In the Republican contest to replace longtime Rep. Mark Amodei, who is retiring, President Donald Trump has endorsed David Flippo, a loyalist of the president who has never held elected office. Amodei and Lombardo have backed James Settelmeyer, a former state senator with a long political track record.

The district covers northern Nevada and includes Reno and Carson City, the capital, along with an immense rural expanse.

Trump-endorsed candidates have seen successful in primaries elsewhere, underscoring his unrivaled power over the Republican Party as he enters the last years of his presidency. He easily won the district in the 2024 presidential election.

The GOP nominee has a good chance of winning in November, as registered Republicans outnumber Democrats by 70,000 in the 2nd District. A Republican has held the seat since the district was created in the 1980s.

Still, Democrats hope to entice the large number of nonpartisan voters in the district this fall. Their candidates include Teresa Benitez-Thompson, a former majority floor leader of the Nevada Assembly, and Greg Kidd, an investor who ran in the last cycle as a nonpartisan.

3rd Congressional District

Nevada’s other three members of Congress, all Democrats, are expected to win their primaries easily.

In the 3rd District, Republicans are battling to determine who will face Democratic Rep. Susie Lee in what is considered the most competitive congressional district in Nevada because of its narrow Democratic registration advantage, its high number of nonpartisan voters and a history of razor-thin election margins. In 2024 both Lee and Trump won narrowly.

Candidates include Trump-backed Marty O’Donnell, a composer who worked on the “Halo” video game series and ran unsuccessfully for the seat in 2024; Jeff Gunter, a dermatologist and former ambassador to Iceland; neurosurgeon Aury Nagy; and businessperson Tera Anderson.

The candidates ran on border security, energy independence and decreasing the federal debt.

Attorney general

With Ford term-limited and running for governor, the opening has prompted competitive primaries for the state’s top law enforcement post.

The Democratic side features state Senate Majority Leader Nicole Cannizzaro and Treasurer Zach Conine. Both campaigned on promises to take on the Trump administration, following in the footsteps of Ford, who filed numerous lawsuits against the federal government.

For the Republicans, Trump-backed attorney Adriana Guzmán Fralick faces Douglas County commissioner Danny Tarkanian. Tarkanian, son of legendary University of Nevada, Las Vegas basketball coach Jerry Tarkanian, previously ran unsuccessfully in multiple congressional races.

Both candidates campaigned on “election integrity,” casting doubt on voting security. Nevada is one of the swing states in which Trump falsely claimed the 2020 election was stolen, despite officials finding no evidence of widespread fraud.

Tarkanian promised to investigate voter fraud allegations, while Guzmán Fralick vowed to seek passage of the SAVE Nevada Act, which would be similar to changes Trump has sought at the federal level.

Her legislation would require all votes to be counted on Election Day, end universal mail ballots and eliminate automatic voter registration. It would almost certainly hit a dead end in the Democratic-controlled Legislature.

GOP secretary of state candidates question Nevada’s elections

Several Republicans are running for secretary of state, the office that oversees elections, including some who falsely claimed the 2020 election was stolen from Trump. The winner of the primary will take on Democratic Secretary of State Cisco Aguilar.

The GOP candidates include Jim Marchant, a former state lawmaker and perennial candidate who has said the 2020 election “was probably stolen”; Sharron Angle, a former state lawmaker who was part of an effort to block the certification of Nevada’s 2020 election results; and Shirley Folkins-Roberts, an attorney who received Lombardo’s endorsement and has denied there is widespread fraud in Nevada’s elections.

All the candidates support implementing voter ID, which will be on the ballot for the second time in November after the question passed by a wide margin in 2024.

Angle promises to enforce voter ID if voters pass it and supports Trump’s executive order seeking to require documentary proof of citizenship to vote. The courts have so far halted that order, issued last year, from taking effect.

Marchant wants to eliminate electronic voting machines and end the state’s universal mail ballot system. He also wants to require paper ballots, which would be counted by hand, according to his campaign website.

Folkins-Roberts said she will work to keep voter rolls accurate and up-to-date, require voter ID and ensure that election results are delivered on time. She also wants to reverse the automatic voter registration system. In an interview with News 4 Reno, Folkins-Roberts said she believes Nevada’s elections are “good,” but wants to improve voters’ confidence by making changes.
