John Key's refusal to share the stage with the leaders of smaller parties in this year's election debates is not new. In the last election he and Helen Clark jointly decided to take part only in head-to-head encounters.
Key says most votes are cast either for National or Labour and that leaders' debates are a chance for the public to assess two competing claims to the premiership. That's only partly right - and to the extent that it's wrong, it's completely wrong.
In each of the last two elections, roughly 1.8 million voters party-voted either National or Labour. That leaves almost 500,000 who did not. To blithely dismiss more than 20 per cent of the electorate is highhanded and arrogant. The last time we looked, the ballot paper was not constructed in such a way that we chose the Prime Minister before proceeding to cast votes that would decide the composition of the Government.
Voters both deserve and want to see Key and Goff go head to head. It is an important part of the campaign process in a country where the political landscape is still dominated by the two major parties. But that is not all they want and need. In the MMP era, voters are inevitably thinking of how the next Government might be composed. They vote strat-egically, as Key will be advising National voters to do in Epsom.
So the all-party bunfights matter. Watching potential coalition partners in the same room - even in the artificial environment of a television studio - can communicate much about the possibilities (and impossibilities) of certain alliances. It makes for more informed voters.
