Le Mars, IA sits in the Corn Belt. For most of the post-war period it was a Democratic metro — its working-class profile gave it the same political habits as much of its region. That identity has shifted decisively in the last twenty years.
The Democratic margin in Le Mars, IA peaked at forty-four points in 1932. By 1968 the metro had flipped, voting Republican for the first time in many years. The 2024 margin was fifty-four points, the most Republican-leaning result in the metro's modern history.
The economic context is the key. The median household income of $83,251 sits well below state and national norms, and 7% of residents live below the federal poverty line. The shift here is part of a broader realignment of working-class places across the country.
