Yes, this is cliche and derivative, but, for those of you who still remember the
Andre the Giant stickers around your cities or the
Howard Dean ripoff of it, you might find this amusing. My photoshopping skills are awful, so consider this more of an amateur prototype than an implementation:
Imagine a few of these stickers on street lamps in your favorite Republican districts-- warning incumbent Republicans that none of their seats are secure, because there's a tough-talking out-and-proud Democratic candidate with supporters ready to vote him right out of office.
