(via Vondell Swain on Tumblr) I just reblogged this on Tumblr, but it deserves more attention, so I'm posting about it here, too. Someone named Chris Howard on Facebook posted this image:
The map in the top middle is the one I saw on election night. The map on the top left is the way it would look if you broke down the wins by county. It actually kinda looks more red, doesn't it? Over on the right, you have it in shades of purple based on the split -- most of the country looks pretty divided, and it seems to make sense that more of it skewed blue. But it still might not look totally fair that the Democratic president gets to run this apparently very right-leaning country.
Then, the big map on the bottom, shows another level of overlay -- the counties are washed out based on population density. Suddenly, it becomes apparent that those handfuls of counties that skew blue are where basically all of the people are.
