A Herd of Cats was not my suggestion but having researched it, it has its points. Perhaps it needs some explanation. Feel free to explain any other suggestion you like, in comments.
Wiki says, of herding cats:
A saying that refers to a task that is extremely difficult or impossible to do, due to one or more variables being in flux and uncontrollable.
The notion of libertarians, rightwingers, anti-government pundits, anti-EUists, capitalists, freethinkers and patriots able to be herded into one blog is quite amusing. Let’s face it – it would be a herd of cats, each wanting his or her own way.
Self-effacing, n’est-ce pas?
