Winston Peters didn't just beat National in Northland, he thumped them.
And this week, a fired-up Peters showed he is Opposition leader and a one-man-band.
He has put John Key on notice that he is to be his fiercest critic and Northland's staunchest advocate.
Peters is unencumbered of government. His job is that of critic. And he has made sure his caucus won't trouble him — his MPs know their job: agree with the boss, sit back, stay out of trouble.
I was wrong to believe Peters wouldn't win Northland. I also believe I was wrong to think he won't keep it. He will put Northland on the political map and with the leader's parliamentary budget he can make sure it has never been better served. Peters has lost two seats. He must now know how to keep one.
