It’s all over but the shouting -- Tony Abbott has signed the government’s death warrant by creating disunity within the Coalition over the Finkel review. For as the battle-scarred Labor opposition is so fond of saying: we’ve seen this movie before, and there’s nothing to suggest it will end any differently this time.

Abbott knows the old maxim “disunity is death” is more than a glib three-word slogan -- it’s an undeniable political reality.
