The Boise mayor election is upon us. Which candidate has raised the most money?

Before voters head to the polls Tuesday, the two major candidates for Boise mayor are still getting contributions and spending funds in last-minute bids to woo supporters.

Mayor Lauren McLean has outraised her primary opponent, Mike Masterson, by about $240,000.

Both campaigns are spending dollars on campaign ads, pamphlets and postcards mailed to voters.

Lauren McLean: Democrats, trade unions, climate groups

McLean has drawn large donations from Boise doctors, lawyers, developers and executives. She has also received hundreds of smaller donations from locals.

McLean has raised over $500,000, compared with the $355,000 she raised in the 2019 race. The mayor has spent tens of thousands on The Scrap Shop, a local political consulting firm managing her campaign as well as the campaigns for multiple City Council candidates.

The Democratic mayor also continues to receive the support of local party leaders in the nonpartisan race, with new donations from Boise Democratic Sen. Janie Ward-Engelking ($500), Sen. Carrie Semmelroth ($100) and Rep. Lauren Necochea ($100).

After securing a $15 billion investment from Micron for a new fabrication plant last year, McLean has the support of company executives. Sanjay Mehrotra, the company’s CEO, and Manish Bhatia, executive vice president of global operations, both donated the maximum $1,000 each.

Jessica Rolph, the CEO of Boise’s Lovevery toy company, donated $1,000.

McLean has also been endorsed by multiple local trade unions and received $1,000 from the International Union of Operating Engineers, which represents workers in the construction industry.

A high-spending political action committee tied to that union, the Engineers Political Education Committee, also donated $1,000, and gave $5,000 to Boise Fact Check, a PAC supporting McLean. The engineers PAC spent more than $1.6 million on political races around the country last year, according to Open Secrets.

The Idaho State Pipe Trades Association also gave $1,000.

McLean has received donations from prominent political donors outside of Idaho, like Michael Kieschnick, who started the Green Advocacy Project, which is pushing for a rapid transition away from fossil fuels in the American economy. He donated $1,000.

Teresa Heinz donated $1,000. She chairs the Pittsburgh-based Heinz Family Foundation and is married to John Kerry, President Joe Biden’s special presidential envoy for climate and a former secretary of state and Massachusetts senator.

Mike Masterson: Republicans, fire unions, car dealership

Masterson also has received a large number of small donations, as well as contributions from local executives and developers. His campaign has raised more than $260,000.

He has spent more than $35,000 on Gem State Public Affairs, a political consulting firm, and about $24,000 on Logsdon Strategies, a consulting firm based in Portland, according to campaign records with the Idaho Secretary of State.

Thomas Prohaska, the co-founder of the Idaho Trust Bank, donated $1,000.

Materson has also received donations from local attorneys.

Thomas and Barbara Mannschreck, co-owners of Thomas Development Co., both donated $1,000 to Masterson’s campaign. Thomas Development has built multiple affordable housing complexes, including work on Adare Manor, which received funding from Boise when it was built in 2018.

Since leaving office, former mayor David Bieter, who endorsed Masterson, has worked at the developer Gardner Group. Two other executives at the company have supported Masterson with donations, including Brady Southwick and Weston Arnell.

A gun store, Overland Armament, gave Masterson $500.

Masterson got a $1,000 donation from Robert Rebholtz Jr., president and CEO of Agri Beef, a meat company.

Thomas Rebholtz, owner of real estate services company Windermere Powerhouse Group, donated $1,000.

Cornerstone Commercial Real Estate gave $1,000.

The Building Contractors Association Southwest Idaho, a large Republican donor, gave $1,000.

Victor McCraw, who ran unsuccessfully against Matt Clifford in last year’s Ada County sheriff race and who was also a finalist for Boise’s police oversight office director last spring, gave $1,000.

Masterson has the support of Boise’s police and fire unions, and money from firefighters has been streaming in the door. Masterson’s campaign headquarters is also at the local union’s office.

The Nampa Firefighters PAC, the Meridian Firefighters Local 4627, Coeur D’Alene Firefighters PAC, Idaho Falls Firefighters, Pocatello Firefighters and Kent Firefighters Local — near Seattle — all gave $1,000 donations.

ES-O-EN Management, which is controlled by Carl Nicolaysen, gave $1,000. Nicolaysen also separately gave $1,000, as did Pamela Nicolaysen.

Lynn Bradescu, a real estate agent and president of the Ada County Lincoln Day Association and a precinct committeewoman for the Ada County Republicans, has given Masterson $1,000.

Masterson got additional new donations from retired police officer Greg Oster and current officer Kip Paporello.

He has also been endorsed by Dirk Kempthorne, a former Idaho Republican governor.

The two other mayoral candidates, Joseph Evans and Aaron Reis, have not met the minimum $500 fundraising threshold required to file contributions, according to campaign records.

Two PACs spend heavily in race

A PAC called the Idaho Majority Club has quickly raised money in recent months, pulling in $78,000 since August. The PAC has spent more than $59,000 supporting Masterson since the end of October.

Some of its biggest contributors include major Idaho Republican donors like Larry Williams, who gave $10,000; the Idaho Land Fund, which gave $10,000; and Fairly Reliable Bob’s, a car dealer, which gave $5,000. The $1,000 limit on contributions to candidates in each election cycle does not apply to PACs.

Boise Fact Check, which is supporting McLean, has raised nearly $407,000. Of its donations, $326,699 are in-kind donations from the Conservation Voters of Idaho Action Fund. The organization previously told the Statesman it has paid for digital and TV ads for Boise Fact Check.

The conservation PAC, in turn, has received $465,000 from the League of Conservation Voters Victory Fund, a national environmental super PAC focused on races across the country. Some of its biggest donors include the Green Advocacy Project — whose founder donated to McLean — as well as Waterfront Strategies, an advertising mega-donor for Democratic causes, according to filings with the Federal Election Commission.

The Idaho conservation organization also received a $10,000 donation from BVA Development, the company run by Tommy Ahlquist, and $10,000 from A.J. Balukoff, a prominent Democratic donor.
