Opposition Leader Bill Shorten has dealt another blow, with his new tax policy wiping thousands of dollars from voters’ pockets.

New data has revealed 90,000 voters in 13 of the nation’s most marginal seats would have $2,000 wiped from their income.

The Opposition leader is now back-tracking and Prue MacSween tells Chris Smith she isn’t surprised.

“The backpedalling is fascinating, isn’t it.

“He’s trying to play this class welfare thing. But a lot of these people being hit are traditional Labor pensioners.”

Prue says Labor’s new tax move has left their Batman by-election candidate Ged Kearney with a battle on her hands.

“He’s really hung her out to dry,” says Prue.

“I think it’s sad they’re giving a free run to the Greens. I think they’re worse than Labor but it’s hard to tell these days.”
