The MP predicted the election result in western Sydney would come close to the wipeout Labor suffered in the NSW state election, with the Eddie Obeid ICAC scandal also affecting the vote.
"It is going to be a flaying," the MP said.
Another Labor MP also questioned the sleepover, after Ms Gillard said - when she announced the September 14 election eight months out - that she was committed to governing. "We were meant to be about governing, this looks like campaigning," the MP said.
Blacktown Labor councillor Leo Kelly yesterday said the western Sydney sleep-out was "a bit late".
