one of these things is not like the other

I was driving the other day when I got stopped behind this car, which was, in the fashion of the times, bedecked with many an opinionated bumper sticker.





Now, this is not a knock on the politics expressed via bumper sticker. People certainly have the right to express themselves via rear window decal, just so long as it isn't with a "Calvin peeing" logo. However, it occurred to me that one of these bumper stickers was not quite in line with the others. See if you can spot it.








(Note also, that the hood of my car was covered in a fine dusting of yellow pollen. Welcome to springtime in Atlanta. I can't tell if everything is yellow because it is coated in pollen, or if it is actually my eyeballs themselves that are coated.)
