I'm astounded to see the same people showing up day after day with 101% commitment to Labor , regardless of policy, leaders and events.

I'd like to ask these people to explain the following fact -
- in the 2007 election, about 5.4 million Australian voters voted for Labor.
- in the 2013 election, about 3.6 million Australian voters voted for Labor

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?
