One of the fringe candidates is Alfredo Iorio. He doesn't have a chance to be mayor, but his poster ads reveal how one segment of the population imagines solving the city's problems, which are legion--or not solving them.
(below) "Enough Humiliation for Romans"
The most creative effort of the Iorio campaign is the poster below. It works two ways. On the one hand, the outer-space-like creature stands for unwanted immigrants and aliens: "Let's stop the Alien Invasion." On the other hand, the poster accuses other mayoral candidates, including two who have a chance of winning, as well as the former mayor (who isn't running, of course), of being aliens: "They come from another planet/They want to conquer Rome."
Invaders everywhere! Welcome to sophisticated Rome politics!
