John Armstrong also reviews Key's prospects and performance in today's NZ Herald
Key also knows he must tighten up his act. He does not need telling that, even with the best of planning, in the heat of an election campaign things can suddenly go wrong and mistakes are easily made. His relative inexperience makes him more vulnerable to slip-ups, which Labour will seize on as evidence he is not up to the job.
Experience _ or the lack of it _ then becomes the issue. That could be fatal. As Barack Obama is finding, warm fuzzies only get you so far.
