Baltimore City's D+72.4 margin in 2024 reflects a dense, majority-Black electorate shaped by decades of deindustrialization and urban policy — making it a reliable anchor of Maryland's Democratic statewide coalition.
The Democratic margin in Baltimore city peaked at 100 points in 1904. By 1960 the county had flipped, voting Republican for the first time in many years. The 2024 margin was seventy-two points, the most Democratic-leaning result in the county's modern history.
The economic context is the key. Baltimore city's median household income of $62,177 sits well below state and national norms, and 20% of residents live below the federal poverty line. The shift here is part of a broader realignment of working-class places across the country. The county's voting pattern over the last decade is most similar to that of St. Louis city and Claiborne County.
