Marco Erickson: Republican Nominee for Idaho House District 33 Seat B

Rep. Marco Erickson, a three-term incumbent, won a contested May 19, 2026 Republican primary for Idaho House District 33 Seat B, defeating Jilene Burger 2,465 votes to 2,093 (54.08% to 45.92%), according to certified Idaho Secretary of State results. He faces Democrat Todd DeVries in the November 3, 2026 general election.

Background

Erickson, whose full name is Marco Adam Erickson, was born in Montana and raised in Boise. He holds a bachelor's degree from Montana State University and a master's degree in psychology from Walden University, according to his official Idaho Legislature biography. He began his career providing direct mental-health services before moving into state-government and nonprofit program management, working on issues including anti-bullying efforts, HIV, homelessness, suicide prevention, drug and alcohol treatment, Medicaid, and maternal and child health; he currently works as a coalition program director. He has been married 24 years and has five children, ages 11 to 22.

Legislative Record

Erickson currently serves as vice chair of the House Health and Welfare Committee and also sits on Judiciary, Rules and Administration and Local Government, per the Legislature's 2026 roster. In the 2026 session, he sponsored HB 723, which established oversight and a "bill of rights" for youth in residential treatment facilities following an Office of Performance Evaluations report on safety gaps; it passed the House 42-25-3, cleared the Senate, and was signed by Gov. Little on March 26, 2026. He told the Idaho Capital Sun, "We have the opportunity to protect many, many children in the future, and for future generations of people who are entering into a mental health treatment facility."

In 2023, the Legislative District 33 Republican Committee sent Erickson a 55-page packet alleging 14 platform violations tied to his votes on several bills. He responded to the Idaho Press: "I'm not really giving a lot of attention to negativity, because I'm just focused on what we're doing well."

Electoral History

Erickson first won the District 33 Seat B House seat in 2020, defeating incumbent Rep. Bryan Zollinger in the Republican primary 2,509 votes to 2,375 (51.4% to 48.6%) before winning the general election with 65% against Democrat David Roth. He ran unopposed in both the primary and general elections in 2022. In 2024, he defeated Burger in the primary 2,377 votes to 1,916 (55.4% to 44.6%) and ran unopposed in the general, according to Idaho Secretary of State canvass records. His 2026 primary rematch against Burger was his closest race since first winning the seat.

In a May 14, 2026 primary debate covered by LocalNews8, Erickson said: "I'm the true voice of you as the taxpayers. I've cut taxes for six years in a row, multiple billions of dollars. But I've also done a good job making sure Idaho performs well and being a part of a good team there. I'm in leadership for a reason. That means my colleagues and the leadership in the Statehouse believe in me."

Endorsements

In 2020, when Erickson first challenged incumbent Rep. Bryan Zollinger, U.S. Rep. Mike Simpson backed his campaign, telling the Post Register: "I'm impressed that Marco knows the key role that the INL and agriculture play" in the district's future.

Erickson's 2026 campaign finance filings with the Idaho Secretary of State's Sunshine portal show a beginning cash balance of $0.42, total contributions of $30,282.40, $1,400.00 in loans received, and total expenditures of $34,337.12, leaving an ending cash balance of $1,000.42 and $1,400.00 in outstanding debt.
