How Atlas thought about thisflip_analysis
Question interpretation
Analysis of Miami-Dade County, FL's 2020 to 2024 presidential partisan swing — magnitude, geographic concentration within the county, demographic correlates, and the multi-cycle trajectory that contains it.
Ambiguity notes
- Interpreting 'what drove' as magnitude, geographic concentration, and demographic correlates of the shift — not speculation on campaign, policy, or messaging causes.
- 2020 to 2024 swing defined as margin_2024 minus margin_2020 under the (dem-rep)/total margin convention (positive = D lead, negative = R lead).
- Miami-Dade crossed from approximately D+7 in 2020 to approximately R+11 in 2024 — a shift of roughly 18 points; flip_analysis section treats this as D to R.

Three sentence slots: magnitude of the 2020 to 2024 shift, sub-geographies within Miami-Dade that concentrated the shift, and peer comparison if available. Never speculate on causes.
- 04historical_trend
Name the 2016 inflection explicitly — the shift did not begin in 2020. Describe the 2008 to 2024 arc with specific cycle-by-cycle margins.
- 05demographic_lens
State Hispanic share and foreign-born share versus Florida overall. Do not describe the Hispanic population as monolithic.

Narrative angle
Headline emphasis. Magnitude of the 2020 to 2024 margin shift and where within Miami-Dade the shift concentrated
Frame. Miami-Dade's 2020 to 2024 swing as a magnitude and a set of sub-geographies within a longer arc starting in 2016, not a causal story.
