Lawn Signs and Bumper Stickers

I've noticed that some of my neighbors are keeping their presidential campaign signs inside the front window, rather than out on the lawn, probably because they don't want them removed. I've even heard of bumper stickers being scraped off by those who disagree with the point of view they express.

Human nature being what it is, it shouldn't surprise us that these low, sneaking tactics are thousands of years old. A campaign poster in ancient Pompeii (Corpus Inscriptionum Latinarum 4.3775, tr. Jo-Ann Shelton) said:

His neighbors urge you to elect Lucius Statius Receptus duovir with judicial power. He deserves the position. Aemilius Celer, his neighbor, wrote this. If you spitefully deface this, may you become very ill.

Although I myself never put up lawn signs or attach stickers to my car's bumper, I heartily approve of Aemilius Celer's curse.
