Presidential election results are often pictured through electoral college maps, a useful and simple tool. Looking at the competition of the two parties throughout time provides a quite interesting exercise. Certain states turn blue, then red, then blue again. Others stay the same color.

Since 1992, however, third-parties have had quite a rough run. This graph shows the third-party vote after that year:
