If there's one thing the debacle with the Conservative Party has demonstrated, it's that politics is not a game for amateurs.
There's a lot of factors that provide the staying power in New Zealand politics.
It can be that your party will never sail to magnificent heights, such as Peter Dunne's United Future, but Mr Dunne is well-liked in his own electorate.
A man who every year gets dressed up in green tights as one of Santa's elves on his sleigh for the Johnsonville Christmas parade is a man with an eye on his electorate - thus he stays an MP.
It could be that you time it right with a disenfranchised public. Ultimately, this is how governments are formed, when so many people are disenfranchised they vote a party out.
