- The title of this episode refers to the two major American political parties: Republicans (Red) and Democrats (Blue). These colors are also often coordinated to states depending on which party is usually the most victorious. Also, at the time the story takes place, there is a dispute over the winner of the presidential election, which could be seen as a metaphor for the turmoil and uncertainty within the band.
