I’ve been thinking a bit about the possibility of a double dissolution. Given the complete incoherence of the Opposition, anything could happen, but it’s hard to see them agreeing on amendments that would be workable in any way. And equally it’s hard to imagine any outcome from a DD election other than a crushing victory for the government. Even so, a Senate majority looks out of reach.
That leaves them with two options after the election. They could use the joint sitting mechanism to pass the ETS bill rejected twice by the Senate. Alternatively (or subsequently), they could sign on to an agreement at Copenhagen and introduce new legislation implementing that agreement, relying on support from the Greens (or, in the event of a post-thrashing change of heart, the Opposition). The latter option looks a lot more appealing in many ways.
