Consider, for example, the simple Hobbits. They're innocent, ordinary folk who just want to be left alone, much like contemporary Tea Party and Christian conservatives, but they're hounded and pursued, threatened and persecuted, by the fearsome Nazgul, just like the IRS hounds, audits and makes life miserable for any group which identifies itself as conservative and which opposes the current administration.
Meanwhile, the all-seeing eye of Sauron surveys the land of Middle Earth. Almost nothing escapes its notice, just like our NSA, sweeping the cyber-landscape, searching relentlessly for those who would deny Sauron the Ring of Power.
Sauron, whom good manners prevents me from identifying, but you can figure it out, seeks the Ring that will make him unstoppable and invincible, the same effect, if you think about it, that a Democratic sweep of Congress in 2014 would have.
Meanwhile, the Huru-Kai (i.e. Rush Limbaugh's "low information voters") are unleashed on the land as the means by which Sauron seeks to crush all opposition and carry out his quest for power.
I'm sure there are other parallels between our current perilous state of affairs and the frightening goings on in Middle Earth. Readers who think of some are welcome to submit their ideas through the Contact Us button.
