For example, take a useful look at CityLab's Congressional Density Indicator [1]. There are zero "pure urban" districts that are represented by Republicans, regardless of the state (red, blue, purple), and there are nearly none among the "urban-suburban mix" districts (again regardless of state).
Viewed through yet another lens, by percentage of landmass, Alabama is more is more "blue" than Illinois and Oregon [2]. Your characterization could use a little more thought and refinement.
