The Australian Democrats lost their last sitting MP last week, when South Australian Upper House MP David Winderlich resigned from the party. Andrew Bartlett wrote about this milestone at Crikey’s The Stump, and on his own blog.
Now it appears that One Nation, whose last sitting MP, Queensland state member Rosa Lee Long lost her seat in the March election, is to be de-registered by the Electoral Commission.
Both parties in very different ways shook up the political system when they emerged about two decades apart. The emergence of both parties also represented significant cultural fractures, as well as an inability of the two party system to contain conflict and dissensus.
It could be argued that their eruption into the political system was their most significant moment, though, obviously, the Australian Democrats made contributions to governance through their balance of power role in the Senate (which also brought them to grief). Fundamentally, neither was successful in sustaining itself as a long term political player, which to my mind, raises some interesting questions about the link between party structures and social bases.
