In a movie or book, "The MacGuffin" is the thing the hero wants. Usually the villain wants it too, and their conflict over who will end up with The MacGuffin forms the basic spine of the story. In Raiders of the Lost Ark, the MacGuffin is, of course, the Lost Ark. Indy wants it; the Nazis have it. This basic conflict over simple possession animates a two hour long movie. Alfred Hitchcock noted -- counterintuitively, when you first hear this -- that the specifics of the MacGuffin don't really matter at all to a movie. He pointed out that the audience doesn't care at all about the MacGuffin. The hero in the movie itself cares, but the audience doesn't.
A MacGuffin only has one requirement: That it be important-sounding, so that the audience understands he hero isn't engaged in some trivial matter, but that the Stakes Are High. But an important sounding MacGuffin is just another way to increase the audience's emotional attachment to the Hero, not to the idea of possessing the MacGuffin.
And that, of course, explains all you need to know about the abnormal political situation we find ourselves in, and the Cult of Barack Obama. For Obama's fanbois, this is not politics. This isn't even America, not really, not anymore. This is a movie. And Barack Obama is the Hero. And the Republicans are the Villains. And policy questions -- and Obama's myriad failures as an executive -- are simply incidental.
They are MacGuffins only, of no importance whatsoever, except to the extent they provide opportunities for Drama as the Hero fights in favor of them… [it's] about Obama's Hero's Journey in navigating the plot of President Barack Obama: The Movie. As with a MacGuffin in the movie, only the Hero's emotional response to the MacGuffin matters.
