I’ve always wanted to print up a bunch of bumper stickers that say, “Yes, I’m an Idiot” & slap them down behind Obama & Hillary bumper stickers.
Maybe a bumper sticker that says, “Yes, I’m projecting” should be made up & slapped on these signs. But I’m not sure they would understand what projection is.
You should carry cards to put on people’s windshields that say
“Hey, I just wanted to alert you that some jerk stuck a Hillary (or Obama) sticker on your car. I’d hate for you to be driving around looking like an idiot so I thought I’d warn you so you can remove it when you get home.”
I thought was a great idea, until you said they might not understand the meaning. Having that sign is a good indicator of their moronity.
