From Want Fries With Your Vote? by Dennis Perrin:
Personally, I don't see the point to political yard signs. Yes, it announces your preference, but it also solidifies your spectator status. All you are doing is providing free ad space to corporate candidates and parties. If one charged a party with yard rental fees, I'd understand the allure. But instead, people willingly display brand names that have little if any real connection to their personal lives. It's analagous to wearing NFL or NBA gear -- which is fine, if you like the look. I just wonder how long it will be before we simply cut to the chase and have bar codes tattooed to our foreheads.
