The Political Wizard of Oz?

F3 pointed out to me a few weeks ago that there are, apparently, political allegories contained within the book, the original stage show, and the film The Wizard of Oz. Wikipedia has an article on the subject. I had hoped to post this on Tuesday, but I worked nearly thirty hours on Tuesday and Wednesday, so I didn't get around to it until now.

Me? I've never actually seen the movie; I was astonished to read through the article and find that this Baum character was actually writing about stuff that I'd learned in my AP US History class in high school (gold standard, William Jennings Bryan, Teddy Roosevelt, Standard Oil, et cetera). I figured he was just really drunk or something!
