Australian Federal Election 2010: Jeremy gives us all something to mull over before we vote

From "Isn't a vote for the Greens a wasted vote?" over at An Onymous Lefty on the 5th July:
"Several of my friends are Labor voters, despite disagreeing with 90% of what the party actually does in office. "Why waste my vote by voting for the Greens?" they ask. "They'll never be in power!"
For progressive ALP voters there's a very simple answer to this question: because voting Greens will make the ALP a more compassionate, humanitarian party.
If you vote ALP regardless of how far to the right they lunge, then they know they can ignore you while they chase conservative votes. If you vote Greens and preference ALP, then you tell them that they need to represent progressive views or risk losing seats to the Greens. They'll {have} precisely two choices then: either adapt by paying attention to what you want and stopping emulating Tony Abbott – or you, along with other progressive voters, will eventually end up electing Greens MPs. (And they'll hold the ALP accountable to your views in Parliament.)"
