It’s time to crank up the stats and run our quarterly election simulations based on polling aggregates of the last three months from all the pollsters that provide state level breakdowns. However, before we do, it’s worth updating our Pollytrend measures as the month of June turned out to be quite the mover and shaker — delivering the ALP its largest voter alienation in the history of the Rudd/Gillard government.

First up, the primary vote trends for the majors (the Greens are pretty flat … see below).

While the ALP primary didn’t quite fall off a cliff, it certainly stumbled without grace or poise down a rather steep hill. The June period saw the Gillard government drop 4 points of primary vote – from 33% down to 29% (give or take a couple of tenths of a percent) in around 30 days. This flowed through into the two party preferred estimates as a slightly smaller loss of 3%. The two party preferred chart is starting to look a little horrific for the Labor side.

Again we see the same pattern emerge where the ALP vote flattens off at some level for a while before taking a hit and flattening off at a new, lower level of support — rinse and repeat.
