Representational Alignment Index: How well each state's House delegation matches 2024 voter preferences | Created with Datawrapper
www.datawrapper.de
The Representational Alignment Index (RAI) measures how well each state's House delegation matches voter preferences from the 2024 presidential election. Lower scores (lighter colors) indicate better alignment between how residents voted and their congressional representation. Higher scores (darker colors) show greater gaps between voter preferences and delegation makeup.

CORRECTED VERSION - Thank you for the feedback!

This is a corrected version of my previous RAI visualization. Special thanks to u/quitefondofdarkroast and u/Deto for their sharp observations that helped identify calculation errors in my original dataset. Their feedback on Texas and Ohio’s scores led me to do a complete verification of all 50 states.

What was fixed:

  • Recalculated all RAI scores from scratch using verified source data
  • Corrected House delegation counts (e.g., New York had 7 Republicans, not 11)
  • Double-checked calculations against multiple examples

Key findings remain the same: Single-representative states tend to show the highest misalignment due to winner-take-all effects, while larger states generally show better proportional representation.

The methodology is sound - it was my execution that needed improvement. This is exactly why peer review matters in data analysis!
