The themes of Much Ado About Nothing are disguise, deceit and infidelity as two long-time adversaries, Bennedick and Beatrice, wind up in love. Which would pretty much sum up any Dream-Team ascension - Rudd and Julia Gillard have spent most of their parliamentary careers eyeing each other suspiciously across Labor's poisonous divide.
Thoughts of which prompt a return to Shakespeare:
Men were deceivers ever,
One foot in sea and one on shore,
To one thing constant never.
Four hundred years old, still the perfectest description of caucus you're likely to hear.
