“Amazon is culling sales data to determine what the election season conversation might be about in each of the 50 U.S. states.
The e-retail giant yesterday launched the Amazon Election Heat Map 2012. The map lists all 50 states, as well as the District of Columbia, and assigns either a red or blue color to each, depending on the number of conservative- or liberal-minded books purchased by citizens. If a state has purchased more liberal books, it'll be shaded blue. States with more conservative book purchases will be shaded red.”
