Turning green?

I'm not sure I should really read over people's shoulders on the train, but in doing so, I discovered that the Daily Telegraph is reporting that the state Labor Party is worried. Worried that any Labor seats with a margin of less than 15% are "under threat". That's a lot of seats. But I'm interested in the Tele's inclusion of the traditionally safe seat of the deputy premier - Marrickville (and the neighbouring Balmain). Their two party-preferred margins are low because the Greens have become the second party, and aren't quite the same as the other seats mentioned. Are they more or less "under threat" than the seats held by similar margins over the Libs/Nats?
