Who Is Nate Marsh? The Prosecutor Running to Take Back House District 43

Nate Marsh's case for himself fits in one sentence from his Ballotpedia survey: "Democrats in Colorado have picked abusers over victims...that stops now!" He is a career prosecutor, and his whole campaign is the courtroom brought to the Capitol. Here is the record behind it, and what he has not said.

The resume

Marsh's biography runs on his site and, in more detail, in the Candidate Connection survey he filed with Ballotpedia on May 22, 2026. He was born in Montana and moved to Highlands Ranch in middle school. He finished at Denver Christian School, took a political science degree from TCU in 2011 and a law degree from the University of Maryland in 2014. In law school he worked at the Baltimore City State's Attorney's Office on economic crimes.

Back in Colorado he joined the District Attorney's Office in El Paso County, where his survey says he handled "cases ranging from DUIs and assaults to first-degree murder" and later specialized in sexual offenses against children. Since 2021 he has been in the Family Violence Unit in Douglas County, prosecuting domestic violence. The Colorado District Attorneys' Council named him Faculty Member of the Year. His title today, per the survey, is Senior Deputy District Attorney.

The office he works in

The Family Violence Unit sits inside the district attorney's office for the 23rd Judicial District, which covers Douglas, Elbert and Lincoln counties and is led by George Brauchler, the county's most prominent Republican officeholder, as our race page lays out. Marsh does not mention Brauchler on his site, and his materials describe his work as Douglas County's, not the office's.

His record as a candidate is partly a record of what the office does. His "Hear from Nate" page describes a clip of him "testifying against a bad bill that would let convicted murderers and habitual violent criminals out of prison," and his survey says he has "fought at the Capitol to stop efforts to reduce penalties for extreme indifference murder and to pass tougher laws ensuring domestic abusers go to prison." He is turning that part of the job into the campaign.

The platform, in his words

Three planks, in his site's order.

Public safety: "support law enforcement and offender accountability," "eliminate mandatory cashless bail" for certain crimes, "require prison sentences for violent offenders," and "fix competency laws that allow dangerous individuals to be released without proper monitoring." In the December version of his survey he tied cashless bail to retail theft costing Colorado "nearly $3 billion a year."

Affordability: he says the state budget "has jumped from $29 billion to $48 billion" under one-party rule while Colorado has become "the third most expensive state," blames "more than 165,000" regulations, and wants hidden fees ended and taxes lowered. TABOR is the center of it: he calls it "the strongest safeguard families have against runaway spending" and says Democrats are "chipping away at TABOR by disguising tax hikes as 'fees.'"

Parental rights: "Stop government and school interference with parental rights and responsibilities." His survey softens the edge, promising to "defend parental rights while supporting the great teachers and schools that make our community strong."

"I trusted Nate in the courtroom. I trust him now to fight for Highlands Ranch and for Colorado." John Kellner, former 18th Judicial District Attorney, on Marsh's endorsements page.

Who is behind him

His endorsements page lists eight. The two police unions: the Fraternal Order of Police South Metro Lodge 47 and the Colorado State FOP, whose endorsement is dated July 7, 2026 over President Michael Deedon's name. The business side: the Colorado Chamber of Commerce, NFIB Colorado, the Independent Electrical Contractors Rocky Mountain, and the Colorado Subcontractor Coalition. One senior-care trade group, the Colorado Placement and Referral Alliance. And Kellner, listed as former 18th Judicial District Attorney and Attorney General candidate, with the quote above.

No elected officials from Douglas County appear on the page. No school board members, no commissioners, no legislators.

The numbers he starts from

The June 30 primary was uncontested on both sides. Marsh drew 9,020 votes on 10,795 Republican ballots cast in House District 43, with 1,775 voters skipping the race. Marshall drew 12,041 on 14,707 Democratic ballots. Primary ballots are not a poll, but they are the only district-level count this year, and the Democratic side was bigger.

The money runs the same direction. Through the Secretary of State's October 5 batch, Marsh had raised $62,383.99 and spent $34,551.20; Marshall had raised $88,562.39 and spent $19,851.19. A third name on the TRACER list, John Cimino, shows zero on both lines; Ballotpedia lists him as withdrawn or disqualified.

What is not there

His site has no issues page beyond the three planks on the home page, no specific bills he would sponsor, and no position on county Questions 200 and 1A, which his opponent sued over. There is nothing on guns, housing, water or transportation. The platform is narrow by design: crime, cost, parents.
