Top Five Presidential Advertisements

In the spirit of a High Fidelity-esq contest, and thanks to the genius of the American Museum of the Moving Image, I propose a challenge to fill a few hours in the days ahead. Every Presidential Advertisement is available here. Take a few days and let me know your selections. I have a few hours to kill here in recovery from the freshers' bender, so I will pass on my choices in short order. May the best advertisement win.
