The trajectory of Maricopa County from 2008 to 2024
How Atlas thought about thistrend

Question interpretation

Presidential margin trajectory of Maricopa County, AZ across the five presidential cycles from 2008 to 2024.

Ambiguity notes

  • Interpreting 'trajectory' as presidential partisan margin across cycles; Senate and Governor data exist for AZ but are not included in this plan.
  • Using the full 5-cycle presidential span [2008, 2012, 2016, 2020, 2024] as specified by the date range in the question.
