|First preference index shows small gains for Labor|
Our First Preference Index experiment is maintaining its record for accurately tracking movements in the major party votes. In our latest polling Labor has improved its vote significantly, the Greens have gone backwards and the Libs are a smidgin under steady, a similar result to Newspoll.
The graph below tells the story. To interpret it you have to understand that it is zero-based at September 2009 and represents movements in votes since then. The graph shows performance relative to each party's past. The Liberal lead is nowhere near as large as it looks.
What appears to be happening from our graph is that Labor is gaining ground against the Greens, but the Lliberals have been fairly steady since June 2011.
