Neco Draconis has a fascinating post about an overview of the presidential candidates, Doppelgangers and Bizarro World Candidates. Each candidate has a mirror or inverse in the other party. Each party puts forth its Technocrat, Populist, etc as part of its menu.
I would add that there are shadows in each set of primaries, Bush and Cheney, Clinton and Gore, and icons, Reagan and JFK. These also affect the movements of the players on the stage.
Comic book and fairy tale characters seem to tap into the same well of images, hence the title.
