This is too perfect, American politics as the war for Middle Earth filtered through the imagination of lewrockwell.com:

Saruman the White: Alan Greenspan

Alan Greenspan was once a white wizard of libertarianism. He preached the gospel of individual liberty and free market economics all over the world. For years, he collaborated with Ayn Rand, and he even wrote an eloquent paean on the virtues of the gold standard.

But as the years passed, he ensconced himself high atop the Fed Tower in Washington and hungrily stared into Sauron’s crystal ball. Seduced by the dark side, he sent forth swarms of counterfeit dollars, more destructive than any horde of uruk-hai, to obliterate our economy and wreck the livelihood of our people.

Of course Tolkien might not approve:

I cordially dislike allegory in all its manifestations, and always have done since I grew old and wary enough to detect its presence.

And then there's this. Best quote from the comments:

Ron Paul will go nowhere for the same reason that pot legalization goes nowhere. Because his natural constituency never gets up off the couch.
