What do tea parties and zombie walks have in common? They both celebrate something really... dead. Tea parties like to believe that the corpse of big-bank capitalism can be raised again, and the same gravy train that derailed (at which time we discovered... THAT'S NOT GRAVY! EEWW!) can be reassembled, so they can get along with their vision of prosperity.
Meanwhile the rest of the country is looking ahead at the next dream, something emergent and potentially wonderful, even though it might not lead to a billion-dollar bonus at some pirate investment bank.
Tea party zombie walkers, put some zip in your step. Carry the corpse with some elan. Why not. Everyone else is laughing. So go ahead. Step up and go for the full Thriller tango.
