I saw this commercial at a movie theatre when I arrived too early. I did not know this ad played during the Superbowl until I searched it on Youtube. 

I think this ad does an amazing job of selling the audience an emotion: A sudden warm and fuzzy liking for the random person sitting next to you. I feel as though the two opposing forces (the Republican and Democrat) represent any conflict between individuals or groups of people. It is an unrealistic scenario that makes the viewer believe that something as simple as an old-fashioned bottle of Coca Cola could easily stop (at least temporarily) a large-scale rivalry. Sharing a bottle of Coca Cola could unite even the most unlikely pair. 

Not only did the bottle of Coca Cola establish a sense of rapport to its drinkers, but it also made the world surrounding it seem much more interesting and engaging. The two politicians, obviously having spent a great deal of time in Washington D.C., took the time to really emerge themselves in a whole different outlook of the city. There is implied humor in the ad as the two men ride one of the buses to go on a tour of the city they should know so well, and they are taking a sudden interest in exploring Washington D.C. 

Coca Cola is advertised as a product that brings people together and sparks an interest in the drinkers' surroundings.
