Peters is not in the business of giving rivals who are after the same votes as him the means to raise their profile. When it comes to winning the seat, Peters is (for once) handicapped by his refusal to reveal his post-election intentions. East Coast Bays is one of National's safest seats. Around two-thirds of both the electorate vote and party vote in the seat went to National in 2011.
Peters would need a big chunk of the National vote to shift his way. But why would National voters back him and risk seeing him install a Labour-led government?
All Craig would need to say is "Vote Peters. Get Labour". Craig may make noises about working with Labour. But that is twaddle. He and the Labour left inhabit different planets. Moreover, if Craig propped up a Labour-led government, it would only happen once. It would be electoral death in East Coast Bays.
The other problem is that Peters would want to win the seat. Doing so would place him in the exact same position he has accused others of deliberately adopting if New Zealand First fell below the 5 per cent threshold. Coat-tailing in a word.
Perhaps worse would be to lose the electorate battle and be out of Parliament because people thought he would win the seat and they did not bother to give their party vote to New Zealand First which then fell below the threshold.
The good news for Peters is that it is becoming less likely National will extend a helping hand to Craig. If so, Peters might well be grateful the decision has been made for him.
