All they would need to do would be to introduce a floor price, as has been discussed. At least Gillard doesn't let donations from big tobacco drive Labor party policy. In any case, I'm no apologist for Labor. I don't vote Labor any more, that's for sure. But at least they have shown moral fortitude in comparison to Abbott's complete lack thereof. You need Turnbull back for the Coalition to have a chance at the next election.
