Why do you show Walmart and health food store locations?
Fivethirtyeight.com had talked about the Starbucks-to-Walmart ratio when talking about which states were likely to votes which way. The Starbucks locations do correlate extremely well with Obama votes, but I have not gotten authorization to use that dataset, alas. I did find health food store locations, and am using that in place of Starbucks, but neither it nor the Walmart locations seem to correlate (at least visually) as well as Starbucks did. Hopefully I will get authorization someday…
