Not being particularly scientifically-minded, I really like the third one, David Miller's:
"Imagine a cocktail party of political party workers who are uniformly distributed across the floor, all talking to their nearest neighbours. The ex-Prime Minister enters and crosses the room. All of the workers in her neighbourhood are strongly attracted to her and cluster round her..."
A perfect analogy given the intended recipient, I thought.
