Pajamas Media's PJ Lifestyle has a column that completes the "Lord of the Rings" analogy. The reader comments make for interesting reading, as it brings LOTR fans out of the woodwork.
An article in the Christian Science Monitor claims that "hobbit" is a positive label that doesn't apply to Tea Party members.
“A reference to hobbits who vanquish Mordor, such as Senator McCain made, should be complimentary instead of disparaging,” says Wayne Hammond, recent author of “The Art of the Hobbit” and librarian at the rare books library at Williams College. “Frodo volunteers to take the Ring out of a sense of duty, not only to his own folk but to all of the free peoples of Middle-earth, while Sam, Merry, and Pippin follow him out of love and friendship as well as their own sense of obligation to humanity. Members of the Tea Party seem to share none of these values.”
