At first glance, it’s a pro-McCain sticker. Or is it? Seen from a distance on the freeway, or glanced at in passing, all you’d notice is a picture of McCain and a call for more of the same with McCain (or “MCcain” in this case), presumably showing their approval of a continued Republican administration. Only by squinting at the fine print will you realize that the message is sarcastic, and the owner of the car is actually mocking McCain and promoting Obama. But who can even read print that small while driving at 60 miles per hour?

For these reasons, I nominate this as the “Most ineffective Obama bumper sticker of the campaign.”
