An e-mail: “My wife and I have a theory about bumper stickers. The most common sticker (and they are VERY common everywhere you go – we live in NY and have traveled recently in MA, CT, NY, NJ and DE) are the support the troops ribbons. We have never seen any cars with these stickers who also sport Kerry stickers. Occasionally we see Bush stickers along with ribbons. We suspect that the ribbons are a stealth way to support the President and avoid dirty looks/hand gestures/vandalism. Now this may not be 100% but I suspect there is a heavy weighting for Bush.”
