Latest polls indicate Government could face a massacre in former western Sydney stronghold.
Prime Minister Julia Gillard is spending much of this week in western Sydney, trying to win back support in the vast suburbs of two million people that could destroy her Government in September.
She has booked into a hotel in Rooty Hill, one of the outer metropolitan suburbs that form the federal electorate of Chifley, named after reformist Labor Prime Minister Ben Chifley and held by the party since its creation in 1969.
Chifley is one of Gillard's key battlegrounds: it recorded an 11.6 per cent swing against Labor in 2010, and is now among a series of former blue-ribbon Labor seats under real threat of falling to the Opposition on September 14.
If polling is accurate, an exodus of voters across western Sydney could alone be sufficient to bring down the Government.
