Pictures matter.

The Democrats should "recolor" the US map with a topography of change. Show the strength of the change vote as a darker color, the equivalent of moutains of increasing height. Democratic votes are altitude with a decreasing amount of color as Republican votes increase.

Country and voting lines should be dropped. The red blue map is polarization and shows identity by state.

The topographical map shows the Democrats as strong - increasing amounts of color to represent the strength of Democratic voting with decreasing color for Republican, a less strong image.

Just a thought, a picture is worth a 1000 words but just in case Democrats should drop red-blue from their vocabulary.
