It is an emotive issue, people do not like to see the government 'selling the family silver' and get all wound up about it.
The Greens are pushing it hard (and emotionally).
I voted (yes by the way), only because I like to vote in everything (so I can then whinge about it later), but I have talked to about 10 people who have already thrown their papers in the rubbish. the majority of those told me if they had to vote, they would have voted Yes, a couple said they didn't give a sh*t and a couple said no. When I asked why they didn't bother voting, most (I'd say 7) said they thought we had already chosen a government who said they would do it in the last election.
It will be a resounding No I think, but the turnout will be tiny (in comparison to a general election), maybe even less than local body turnouts. What will that say? That most people don't actually care.
