Don't vote?

Billboards that say "Don't Vote" are popping up around the Twin Cities. According to Clear Channel, who owns the billboards, the signs are simply a client's way of generating buzz, and will be explained shortly. Kinda like the "Ugly kids become DJs" billboards from a few years ago. But maybe the purchasers of these billboards are have a more nefarious reason for doing so. We'll see.
