Key is one of the few National leaders who has been able, through his own personality, to inspire a loyalty in Caucus which in turn has created its own discipline. In other election years when an Opposition senses it has become the Govt-in-waiting there is a jockeying for position among the more ambitious and snide comments about colleagues. Key may be untried, but he knows how to run a team, and get the best out of them, an essential quality for any aspiring PM.
