Washington is the maximum Republicans could theoretically get. Arizona actually is not the maximum Democrats could theoretically get. Both maps include some parts that are actually quite sensible, some parts that make no sense outside of partisan gerrymandering, and some parts that make no sense whatsoever.
Where are the parts that make no sense whatsoever in Washington?
I do see them in Arizona, mostly in the Republican districts where only Republican districts could be drawn anyway, yet still insane things happened. Like Florence.
