Former Routt County Treasurer Brita Horn starts work Saturday supporting President Donald Trump’s re-election campaign in New Mexico, Colorado Politics has learned.

Horn, who sought the Republican nomination for Colorado state treasurer in 2018, will be in charge of organizing the president’s supporters in the northwest part of Colorado’s neighbor to the south.

Horn said she’ll be employed by the state’s Republican Party as a regional field director. She’ll be based in Farmington.

“It is a honor to be called up to be a part of history,” Horn told Colorado Politics. “There are clear indications that New Mexico is in play and can be flipped for President Trump. I am grateful for the opportunity to put boots on the ground and get to work for the win. I’ll be back in Colorado before you know it in November.”

In 2016, Trump lost New Mexico to Democrat Hillary Clinton by more than 8 percentage points, but his campaign has said the state is a top target in this year’s election.

“We love our Hispanics!” said Trump at a September rally in Rio Rancho, near Albuquerque.

New Mexico, which has the highest proportion of Hispanic voters in the country, hasn’t voted for a Republican presidential nominee since 2004.

Horn was one of only four Colorado delegates to the 2016 Republican National Convention who cast a nominating vote for Trump. Elected as a delegate for Trump rival Ted Cruz, Horn switched her vote at the convention, joining three uncommitted delegates while the state’s 33 other delegates stuck with Cruz in the roll call.

Horn was one of six Republicans running for Colorado’s open state treasurer position in the last election cycle. Businessman Brian Watson won the primary but lost to Democrat Dave Young, a former state representative from Greeley.

In January, Horn was among the Republicans who applied to fill a vacancy created when rancher Randy Baumgardner resigned from the state Senate in the wake of sexual harassment complaint. Then-state Rep. Bob Rankin of Carbondale was elected to the position after four rounds of balloting.

A volunteer fire chief and member of the Colorado State Fire Commission , Horn served six years as the treasurer of Routt County, where her tenure was rocked with controversy, including acrimony over a mistake made by her office that delayed paying nearly $6 million to schools and local governments. An evolving dispute with the county’s commissioners culminated in a lawsuit filed by Horn, which contributed to more than $100,000 in legal bills paid by taxpayers to Denver-based law firm Klenda Gessler and Blue to represent Horn.
