It was 12 years ago on Wednesday that Tony Abbott knifed Malcolm Turnbull to become leader of the Opposition and start breaking Australian politics.
It remains broken.
Mr Abbott and his accomplices so poisoned the well that neither of our major parties can propose rational, efficient climate policy.
In private, off-the-record, there are plenty of Labor and Liberal Party members who know what would best be done for Australia to pull its weight on climate change, to our own and the world’s advantage. But both sides are hamstrung by Abbott’s legacy of “Total Opposition”.
