Interesting chart published in Tech Republic. It shows that if you look at the most granular level, there is a high variance in political spectrum: a red (republican) next to a blue (liberal) zipcode, even though at the state level, the political color is pretty clear. When you mix red and blue color together, the result is purple, hence the dominating color in the map below being purple.
However, I believe something is wrong with this map. Too much red near NYC, too much red overall, and no big spot on the West coast. Do you think this map is correct? Or is this an optical illusion due to red zipcodes being larger than blue zipcodes yet less inhabited? In short, is this map a good visual tool for the human brain?
Below is a zoom on NYC and long Island, which seems to confirm my assumption.
