The Center for Michigan Redistricting 'Study' Has Data Errors, Too

This blog previously deconstructed the Center for Michigan study.

Analysis and Rebuttal of the Center for Michigan Redistricting Study

I was looking over the data used to construct this report and noticed several errors. Two state house districts are classified as safe when they in fact changed parties. Three others are listed as changing parties once, when they in fact switched twice.

The specific errors are:

District Error .. Truth
24 Usually GOP Swing
32 Usually GOP Swing
70 Safe GOP .. Swing
108 Usually GOP Swing
110 Safe DEM .. Usually DEM

Curiously, all of the errors favor less competitiveness.
