Tonight President Barack Obama and Mitt Romney will have one last opportunity to address voters directly in the last of the 3 presidential debates.  It will be the last major event before Election Day on November 6th and will initiate the final sprint for the Holy Grail: the Presidency of the United States.

The election process has already been going on for a long time, starting in Iowa in January, and will only be fully completed when the elected president takes office in January 20th, 2013. If you are not completely familiar with the whole process of how the President of the United States is elected, the following infographic, made by Carnegie Endowment, will help clarify this unique but sometime confusing process.
