Mapping the vote

A big thanks to John Sides for pointing out the spmap feature in Stata, which allows me to use GIS data in a platform with which I'm already familiar. Anyway, you may recall that I found a nice little correlation a while back between the location of Obama's field offices and the Democratic surge between 2004 and 2008. I can now map this. In the Colorado map below, the bluer counties are those that saw a greater shift toward the Democrats between 2004 and 2008. The red dots mark those counties with Obama field offices. Not a perfect correlation, but definitely a pattern.
