One lawmaker lost his re-election bid, while several caucus-backed candidates eked out narrow victories when the final results from the June 9 primary election trickled in on Thursday.

Final but still unofficial results updated Thursday morning show that Democratic caucus-backed Senate candidate Roberta Lange and Assembly candidates David Orentlicher and Venicia Considine won narrow victories after initially trailing in the early results. Lange and Orentlicher are guaranteed victories in November because they face no opponents in the general election, while Considine is all but guaranteed a victory in her overwhelmingly Democratic district.

The results also show Republican Assemblyman Chris Edwards has lost his seat to Mesquite Councilwoman Annie Black. An incumbent losing in a legislative primary is relatively rare; only three incumbent legislators have lost their seats in a primary over the last two election cycles.

The results will become official when they are certified on Friday. Until then, here’s a look at who prevailed in each legislative primary.

State Senate District 7

Former Nevada State Democratic Party Chair Roberta Lange defeated Democratic Assemblywoman Ellen Spiegel by a narrow 131-vote margin in this eastern Las Vegas and Henderson Senate district. Lange faces no challengers in the general election.

Lange won 38.3 percent of the vote, with Spiegel at 36.9 percent and Assemblyman Richard Carrillo with 24.9 percent. More than 9,500 votes were cast in the race.

Lange's victory represents a win for the Nevada Senate Democratic Caucus, which had endorsed her. Spiegel significantly outraised both Lange and Carrillo in the race in the first quarter and had a massive war chest on hand.

Assembly District 2

Former Nevada REALTORS president Heidi Kasama won this crowded Republican primary to replace termed-out Republican Assemblyman John Hambrick with 47.9 percent of the vote. Erik Sexton, who works in commercial real estate, secured 27 percent of the vote, followed by Jim Small, a retired member of the U.S. Senior Executive Service, with 19 percent.

Kasama ran with the backing of the Assembly Republican Caucus, while Sexton was endorsed by Las Vegas City Councilwoman Michele Fiore and former North Las Vegas Mayor Mike Montandon. Small had the support of former congressional candidate and businessman Danny Tarkanian and conservative commentator Wayne Allyn Root, among others.

Kasama significantly outraised her opponents in the first quarter, and the Alliance for Property Protection Rights PAC, which is funded by the National Association of REALTORS Fund, inserted itself into the GOP primary in support of her bid.

On the Democratic side, Radhika “RPK” Kunnel, a law school student and former cancer biology professor, won the primary over Jennie Sherwood, a journeywoman electrician. Kunnel secured 35.8 percent of the vote while Sherwood won 31.5 percent. A third candidate, Eva Littman, won 23.7 percent.

Republicans have a good shot of keeping control of this seat come November, given the 2.3 percentage point voter registration advantage they hold in this district. The Assembly Democratic Caucus did not endorse a candidate in the primary.

Assembly District 4

Former Assemblyman Richard McArthur won the Republican primary in this northwest Las Vegas Assembly district with a narrow, 2.3 percentage point victory over Donnie Gibson, the owner of a construction and equipment rental company. McArthur secured 51.2 percent of votes to Gibson's 48.9 percent, a 130-vote margin.

McArthur, a former FBI special agent, has served three non-consecutive terms in the Assembly, two terms between 2008 and 2012 and one term from 2016 to 2018. Gibson, a political newcomer, was endorsed by the Assembly Republican Caucus in the primary.

McArthur will go on to a rematch against Democratic Assemblywoman Connie Munk, who did not draw a primary challenger. She narrowly defeated McArthur in 2018 with a 120-vote margin out of nearly 30,000 votes cast.

Assembly District 16

Community activist Cecelia González won this four-way Democratic primary to replace Democratic Assemblywoman Heidi Swank, who has represented the district since 2012 and opted not to run for re-election.

González secured 50.1 percent of the vote, followed by Joe Sacco, a union trade show and conventions worker with IATSE Local 720 and a REALTOR, with 23.9 percent of the vote. Russell Davis, a two-decade Clark County employee and SEIU member, trailed with 13.7 percent of the vote, and online finance professor Geoffrey VanderPal had secured 12.4 percent of votes cast.

González and Davis had split the endorsement from major Democratic-aligned groups in the race. Both candidates were endorsed by the Nevada State AFL-CIO, while González was also endorsed by the Nevada State Education Association, the Culinary Union and the Nevada Conservation League, and Davis was endorsed by SEIU Local 110. The Assembly Democratic Caucus did not endorse in the primary.

González is likely to win the general election against the one Republican in the race, Reyna “Alex” Sajdak, because of the overwhelming voter registration advantage Democrats have in the district. 

Assembly District 18

Legal Aid Center of Southern Nevada attorney Venicia Considine eked out a victory over Lisa Ortega, a master arborist and owner of Great Basin Sage Consulting, in this four-way Democratic primary to replace Assemblyman Richard Carrillo, who lost a primary for state Senate.

Considine won with 39.4 percent of the vote, while Ortega secured 37.4 percent and Char Frost, a former campaign manager and legislative staffer for Carrillo, secured 15.4 percent.

Considine ran with not only with the backing of the Assembly Democratic Caucus but SEIU Local 1107, Nevada State Education Association, Planned Parenthood Votes Nevada, the Culinary Union and the Nevada Conservation League. Considine had also raised nearly one and a half times as much as Ortega during the first quarter of the year.

Assembly District 19

Assemblyman Chris Edwards won't be returning to Carson City next year after he was defeated in the primary by Mesquite City Councilwoman Annie Black. Black won with 61 percent of the vote to Edwards' 39 percent.

Black ran to the right of the already conservative Edwards, who has served in the Assembly for the last three terms. Black's victory represents a significant upset in the race as incumbents rarely lose their primaries.

Black is essentially guaranteed to go on to win the general election in November, as there are no Democrats or third-party candidates in the race.

Assembly District 20

UNLV law professor David Orentlicher, who was running with the backing of the Assembly Democratic Caucus, won this Democratic primary with 46.5 percent of the vote, defeating Emily Smith, the CEO of the Nevada Blind Children’s Foundation, by 7.7 percentage points. The seat is currently occupied by Assemblywoman Ellen Spiegel, who lost her primary for state Senate.

Orentlicher ran with the backing of almost all of the major Democratic-aligned organizations, including the Nevada State AFL-CIO, SEIU Local 1107, the Culinary Union, Planned Parenthood Votes Nevada, NARAL Pro-Choice Nevada and the Nevada Conservation League. Orentlicher raised about $5,000 in the first quarter of the year and had about $23,000 in cash on hand, while Smith raised only about $1,000 and had only $700 in the bank.

No Republican candidates filed to run in this Paradise-area seat, meaning Orentlicher will be essentially guaranteed a spot in the Legislature.

Assembly District 21

Attorney Elaine Marzola won the two-way Democratic primary in this race to replace replace Assemblyman Ozzie Fumo, who is running for Nevada Supreme Court.

Marzola received most of the Democratic-aligned endorsement in the primary, including from the Assembly Democratic Caucus, the Nevada State AFL-CIO, Planned Parenthood Votes Nevada, the Culinary Union and the Nevada Conservation League. 

Her opponent, David Bagley, is the director of operations for the stem cell diagnostics company Pluripotent Diagnostics and was also Marianne Williamson’s Nevada state director for her presidential campaign last year. He ran with the support of the Nevada State Education Association.

Marzola won 70.6 percent of votes cast, with Bagley at 29.4 percent.

Marzola will go on to face Republican Cherlyn Arrington in the general election, though Democrats hold a significant voter registration advantage in the district. Fumo defeated Arrington by 12.6 percentage points in 2018.

Assembly District 26

Republican Assemblywoman Lisa Krasner successfully fended off a primary challenge from Dale Conner, obtaining more than 83.7 percent of the vote in the Republican primary for this Reno-area district.

Krasner will advance to the general election to face off against Democrat Vance Alm.

Assembly District 31

Former Assemblywoman Jill Dickman won this three-way Republican primary to represent this Sparks-area Assembly district. Dickman secured 51 percent of the vote, followed by Washoe County Republican Party treasurer Sandra Linares with 34.1 percent of the vote and businessman David Espinosa with 14.9 percent of the vote.

Dickman is hoping to reclaim the seat she held for one term and lost by fewer than 50 votes to Democratic Assemblyman Skip Daly in 2016 and again in 2018. Daly did not face any primary challengers in the race.

Assembly District 36

Assemblyman Greg Hafen defeated challenger Dr. Joseph Bradley in the Republican primary in this rural Nevada Assembly district, which covers portions of Nye, Clark and Lincoln counties. Hafen was appointed to the seat after brothel owner Dennis Hof died weeks before the election but still won the seat.

Hafen, a fifth generation Nevadan and general manager of a Pahrump water utility company, won with 54.9 percent of the vote, while Bradley earned 45.1 percent.

Hafen is essentially guaranteed to go on to win the general election as no Democrats or candidates from other parties filed to run for the seat.

Assembly District 37

Andy Matthews, former president of the Nevada Policy Research Institute, has won the Republican primary in his swingy Summerlin Assembly district. Matthews secured 49 percent of the vote, while former television reporter and congressional candidate Michelle Mortensen won 26.3 percent.

Matthews secured a long list of endorsements in the primary, including from former Attorney General Adam Laxalt, several Trump campaign officials including Corey Lewandowski, Las Vegas City Councilwoman Michele Fiore and several current and former state lawmakers. He also was a top legislative fundraiser in the primary, outraising all other Republican Assembly candidates, including current office holders.

Matthews will go on to challenge the incumbent, Democrat Shea Backus, who won the seat from Republican Assemblyman Jim Marchant by 135 votes in 2018. Democrats hold a narrow 2.2 percentage point voter registration advantage in the district, making it one of the swingiest Assembly seats this election cycle.

Assembly District 40

Former law enforcement officer and one-term Assemblyman P.K. O’Neill appears to be heading back to the Legislature in this heavily-Republican Assembly district after defeating his lone Republican primary opponent, attorney Day Williams.

O’Neill filed to run for the Carson City-area seat on the last day of filing, after incumbent Al Kramer announced he would not run again due to family reasons. O’Neill served one term in the Assembly between 2014 and 2016, but lost to Kramer amid a backlash against Republican candidates who supported former Gov. Brian Sandoval’s large K-12 focused tax increase in 2015.

O’Neill won 54.2 percent of the vote, while Williams won 45.8 percent. O'Neill will go onto face Democrat Sena Loyd in the general election.

Updated 6-10-20 at 6:52 p.m. to correct that Assembly District 20 is primarily in Paradise, not Henderson.
