During 2007 I regularly visited a number of political blogs. One of the best was Possum Comitatus Possums Pollytics
Pos has a wonderful understanding of statistics and the analysis of time series.
He has finally excelled himself with the Pollcoaster - "the ALP two party preferred vote from January 2000 through to the 2007 election". As he says it gives a whole different perspective.
Note: sunlies is the Sunrise Anzac Day fiasco.
