Did anyone notice the change in assessment from the PM yesterday? She has moved from her claims that Labour+Green=National in all the polls she has seen to a new, and more accurate formulation. She is now saying Labour+Green+some other support = being competitive. Being competitive means being reasonably close, not the same.
All polling we know of is showing National well ahead of Labour+Green and that gap has grown a little in recent days (as has the proportion of the Green vote in the Labour+Green mix).
