Amy and I went to the opening of a display put together by Professor Jane Caputi called "Political Circus." It's a collection of campaign materials from the last year or so, and I've put out a few samples below. If you're in south Florida, I recommend you see the show. It's at the Ritter Gallery on the FAU campus, and I'm uploading more pictures to the Flickr account where these are. I'll add the link as soon as I figure out how to do it.
By the way, these weren't even the most disturbing ones. I'll get to them later.
Try this link for some more photos. Let me know if it doesn't work.
