This question strikes right to the heart of a perennial dilemma for me: in most elective offices, there isn't any candidate whom I want to vote for. They're all rats!
In Mexico, the problem of rat candidacy is arguably even worse than in the U.S., and the people there are consequently perhaps even more frustrated than we are. Sergio Chamorro, of Mexico City, had an inspired solution: he's running Morris, his cat, as the anti-rat candidate. And his solution has in turn inspired others in Mexico to put up their own pets and farm animals as candidates.
Think about it. Which sounds better to you? A Congress populated by the likes of Pelosi, Reid, Graham, McCain, and Feinstein – or by Fido and Fluffy? I know which makes me feel safer!
