Star Trek IV: Save the Whales is another one. I'm having a real hard time coming up with titles that are either liberal or conservative. I tend to watch a lot of Action, Sci-Fi, and Fantasy, so unless there's an overt political message (there usually isn't), I don't notice it. Serenity could possibly be seen as conservative, though the backstory, I think, falls more in line with the Civil War than anything else.
EDIT: The thread title and mention of Clinton who knows how many times is what's making those ads show up. That and whoever mentioned those authors names.
Let's try this. Joss Whedon, Buffy, Angel, FireFly, Serenity, X-Men. Maybe that'll mix things up a bit.
