The St. Louis media market straddles the Missouri-Illinois border, blending a heavily Democratic city center with competitive suburban counties that have shifted markedly in both directions over the past three federal election cycles.
The Democratic margin in St. Louis peaked at thirty-four points in 1964. By 2016 the market had flipped, voting Republican for the first time in many years. The 2024 margin was five points, the most Republican-leaning result in the market's modern history.
The economic context is the key. The median household income of $79,136 sits well below state and national norms, and 11% of residents live below the federal poverty line. The shift here is part of a broader realignment of working-class places across the country.
