Politics of Defeat: The Decline of the Liberal Party in Canada
In 1980, a Saskatchewan writer wrote a brilliant analysis of what had happened to the once great Liberal Party of Saskatchewan. He traced the history of the party from Saskatchewan's entry into Confederation in 1905 up until they were completely wiped out of the Saskatchewan Legislature for the first time in 1978.
His analysis traced how the Sask Libs went from being a broad based rural and urban party to a minor urban rump party ... and finally into the dumpster electorally. It observes how Liberal ranks dissolved and polarized to either end of the political spectrum.
There is a clear similarity to what may be happening with the Liberal Party of Canada as demonstrated in the 2008 Election.
