For one of the very best post-election commentaries, go and have a look at David Beatson's piece at 'Pundit.'
I particularly liked this bit:-
"Roger Douglas was prepared to see a government destroyed rather than compromise on a free-market ideology that no longer commanded support among his political colleagues. The world has changed since the 1980s – but Douglas has not. Outside or inside the tent, he will be seen as part of the old problem, not part of the fresh solution. Key shows wisdom in reaching out in a new direction - to the Maori Party."
