"Can Lapdog, tinnitus, dust, eagle, Johnno H, misty etc please tell me why they think this happened. Why did 1/4 of Labor's supporters walk away in the space of 6 years?"
Your "analysis" is so simplistic.
You need to look wider and have a wider time frame. Politics has its cycle, just as the stock market has.
The cycle will turn the other way in the future, and then it will turn again, as sure as the sun rises from the east everyday.
