This post follows-up on the last one (Density of Earnings) with just one chart. The President's vote share in each of the 67 counties originally analyzed by Ron Pitingolo are juxtaposed with Rob's college degree density metric (degree holders per square mile). See last post for complete explanation of analysis. Results indicate correlation between higher concentrations of educated people and Obama vote shares greater than 50%. The president won in 91% of these counties.
