Try finding out who's behind this

I was minding my own business, reading my Gmail, when I noticed a sponsored link at the top of the email I was reading. Intrigued, I clicked and was taken to a site whose address says it all: http://obamaisacommie.com/?gclid=CPfLoKyA4pUCFQOcFQodFgRaeg. It's a pretty amazing site, and I have to wonder whether it is: (1) the work of a lone wingnut; (2) the work of someone with ties to the McCain campaign or to a 527 sympathetic to that campaign; or (3) the work of a scam artist, trying to find something more effective than one of those emails from Nigeria [possible evidence for the last option can be found at the bottom of the website]. Thinking about the possible audience for this, and trying to imagine someone with whom this would be an effective tactic, is kind of scary.
