Of the alternatives to MMP on the ballot on November 26, John Key will back the supplementary member (SM) voting system. It favours the big parties while still giving small ones a look in.
Jenny Shipley and Helen Clark opposed MMP. But Shipley got a kick out of successfully running a minority government for two years — and getting some significant policy initiatives through. Clark managed three innovative governing arrangements with skill. Key, too, has got the MMP partner-party spirit.
