How we determined the most conservative cities in Montana for 2025
To find the most conservative places in Montana, we used Saturday Night Science – the argument you’d make at a bar – to find the cities with the most conservatives.
We started by making a list of every city in Montana over 5,000 people based on the 2019-2023 American Community Survey. That left us with 18 cities and towns.
We then measured the voting record and MIT election data to determine which places rock the most rightward in their allegiances by:
- Percentage Of Votes For The Republican President In 2020
Because no voting data exists at the city level, we used county-level election results from the 2020 election. We assigned every city in a county the percentage of votes that went to the Republicans, effectively extending the county’s results to the city level. In cases where larger cities encompassed an entire county, the election outcomes accurately reflected the city’s political landscape.
Next, we ranked each city from 1 to 18 for each criterion, where number one was the most conservative.
The winner, Sidney, is “The Most Conservative City in Montana For 2025”. The most liberal place in Montana was Missoula.
We updated this article for 2025. This report is our tenth time ranking the most conservative places to live in Montana.
