Tommy Christopher and Caleb Howe over at Political Machine have a few ideas about what it might be:
#5 - Ultra-Fast Ron Paul Blimp - Those guys just don't give up.
#4 - Dennis Kucinich - I know, this seems obvious, but remember Occam's Razor. When you hear hoofbeats, look for horses, not zebras.
#3 - A commemorative Obama plate - The commemorative plate is another obvious guess, but remember, sometimes a cigar is just a cigar.
#2 - Port-O-Potty Creature - With all of those cans, and all of that co-mingling bio-waste, it's a good bet that something evolved out of there. If so, it was probably making a beeline to get CPAC tickets.
