This allows you to visualize the election results in various districts. You can switch between LDs, CDs, and counties. That is, state legislative districts, US congressional districts, and counties.
In all cases, the color code corresponds to the results from a November 2022 statewide race. You can switch between the governor race and the US senate race. This allows you to compare one district to another without worrying about district-to-district variations in candidate quality. OTOH this doesn't solve all the world's problems, since the overall average color of the state remains sensitive to the quality of the statewide candidates. I reckon the state would be several points redder if the Rs had fielded stronger candidates.
Switching back and forth between layers is particularly informative. Among other things, you can see which candidates overperformed and which ones underperformed.
