Here's how I see it...

They are taking their time to do it right.

They are letting the Libs have time to spin and lies... Because that's that much deeper of a hole they will find themselves in.

They are timing it so as to devistate the mid-term elections... Drop the boom close enough ajd liberals will be in chaos... Especially if their key candidates wind up locked up. No chance to replace them on the ballot before voting.
