This thematic map illustrates the political party of the governors in the continental United States in 2007.  Thematic maps are used to show how a specific theme relates to a specific geographic area. They can also be used to compare patterns on two or more other maps. We can deduce from looking at this map that much of the United States was virtually split in terms of political party alignment in 2007.
