This week, Montana's Office of Public Instructions Superintendent Denise Juneau told the Associated Press she would be challenging sitting U.S. Congressman Ryan Zinke for his seat. Juneau said her campaign would focus on four main issues: "Preparing the next generation for the global economy, access to public lands, protecting privacy and promoting transparency in election campaigns."

In response, Ryan Zinke explained what he would campaign on.

"I think we should focus on three things: support and defend the Constitution of the United States against all enemies, foreign and domestic. The Constitution should be more than words. It represents our nations values and individual rights. Secondly, I think we need to promote a free and prosperous economy. Unless we have an economy that is growing and is prosperous, you can't afford a strong military, you can't afford to keep the promises we've made, and we've made a lot of promises as a country," Zinke said. "Lastly, I think we need a strong defense. Defense is both national defense and military, but also securing our southern borders. If we focus on those core three things, I think Congress and our country would be stronger."

Since 1889, republicans have dominated Montana's lone congressional seat, while losing to only five democrats. The last time a democrat filled the position was during Pat Williams's last year in office, back in 1997.
