Not bad politics from the opposition

Comments on Joe Kelly "Coalition 'will rescind mining tax' if Tony Abbott defeats Julia Gillard", 1/07/2010, http://www.theaustralian.com.au/politics/coalition-will-rescind-mining-tax-if-tony-abbott-defeats-julia-gillard/comments-e6frgczf-1225886559093
It is normal politics, given that the government is likely to make significant changes to the mining tax it proposed.

By saying it will rescind the tax, the opposition will add further pressures on to the government to back down.

The opposition could change its stance once the tax has changed significantly as expected. They can say it is not the RSPT, the big tax on mining as it once had been announced.

Of course, the more the changes to the original RSPT proposal, the more the government back down and the better it would be for the opposition.

Not too bad political tactics from the opposition.

It may also have an effect forcing the government to improve the tax more significantly to make it better.
