I have noticed that the bumper stickers in the Borders parking lot are overwhelmingly liberal, and that progressives seem to have more bumper stickers than conservatives. (This makes sense, of course, since nobody prints “I love big business” or “Arrogantly Myopic” stickers.) I have two of them. My first one asks: “Do you have evidence to support that claim?” The other reminds people that 1/20/09 is Bush’s last day.
Or perhaps, if you only drive a ferrari (I recently saw a Porsche with a “W” sticker), and can’t dirty it, what bumper sticker have you seen recently that you like? I like the yellow ribbon closed at both ends that says: “Endless war.”
