The judge assigned to the case asked the perspective candidates if anyone in the group had bumper stickers on their car and, if so, what they said. It's a story that often comes to mind when I end up waiting at a red light and find myself reading some sort of statement on a car's bumper, windshield, trunk or license plate. It leaves me wondering about the person in front. And we certainly have a diversity of ideas riding on the roads. For example, there are a lot of drivers expressing emotion about various causes.
Environmentalists have stickers with statements about saving the earth or endangered species.
Pro-gun drivers usually have stickers that support their NRA stance. These folks always make me a bit nervous. I often find myself giving those drivers some extra space. And then there are the people who drive around with old stickers for candidates in past elections. Those always look out of place to me.
