ST. LOUIS COUNTY, Mo. – Less than a week into Donald Trump’s second presidency, new data offers a closer look into last November’s presidential election results, revealing how voter preferences shift across the country.
The New York Times recently released an interactive map titled “An Extremely Detailed Map of the 2024 Election.” The map compiles data available from 42 states and represents around 74% of all votes cast in the 2024 presidential race. It provides a granular breakdown of voter turnout and shifts at the county and local precinct levels.
Nationally, the map shows a notable red shift in the 2024 presidential vote compared to 2020. However, voting patterns varied widely across different parts of the nation.
In particular, St. Louis County took a more nuanced path to retaining its reputation as a Democratic stronghold. It was only one of four counties in Missouri where a majority voted for the Democratic ticket last November, but not without some evolving dynamics.

Support for the blue ticket in St. Louis County dropped slightly over four years from 61.17% with Joe Biden as the presidential candidate in 2020 to 60.79% with Kamala Harris as the presidential candidate in 2024, with roughly 23,000 fewer Democratic votes cast. The numbers indicate that a considerable number of voters inevitably flipped from blue to red in the last election cycle.
The New York Times map further highlights scattered changes in voting patterns across St. Louis County, showcasing a diverse political landscape and some shifting allegiances between the last two presidential elections.
