As the numbers stand, LNP are more likley to lose in a landslide now than under Turnbull
Newspoll had LNP on 49% but morgan allocating preferences on how people responded rather than preferences from the last election hand LNP on 49.5%.
Liberal internal polling of 20 of their most marginal seats had them on 52%, so to suggest LNP would have lost in a landslide under Turnbull is Bull shite
