There's perhaps one finding we can take from the recent opinion polls -- the Greens appear to be doing substantially better on this occasion than in the lead up to any past federal election. This morning's Newspoll put the Green vote nationally at 14% and since the beginning of May it has hovered round the 13% mark.

Yet while the pollsters keep telling us that the Greens are on course to do substantially better at this election than in the past the pundits keep warning us that the eventual Green vote will be less than what is being predicted. Why that is the accepted wisdom of the media experts I'm not sure.
