However, there does appear to be some (Plenty of)gray area in"fair use" , regarding this.

No, you are right. Even if we were to buy YN's arguement (and I clearly don't), I think the copyrighted work (the Corbis picture) is not only being used to parody Kerry's record, but it's being used to parody the actual picture of Kerry sans other protestors.

Thanks for the backup. From what I can ascertain, almost all parody appears to fall under "fair use."

Of course, that doesn't mean someone like Corbis still can't drag you into court, and make your life miserable...
