What drove Miami-Dade County Floridas 2020 to 2024 swing?
How Atlas thought about thisflip_analysis

Question interpretation

What drove Miami-Dade County, FL's presidential margin swing between 2020 and 2024 — magnitude of shift, sub-geographic concentration within the county, demographic composition, and comparison to Florida and national trends.

Ambiguity notes

  • Interpreting 'swing' as the difference in presidential margin between 2020 and 2024 cycles, using the (dem-rep)/total convention.
  • 'What drove' is approached descriptively via magnitude, sub-geographic concentration within the county, demographic composition, and state/national comparison — not causal attribution.
  • Including the full 2008-2024 arc in the historical_trend section so the 2020→2024 swing is contextualized against the longer trajectory.
