If tonight exposes Dotcom as nothing more than a big-noting charlatan who has attempted to hijack the electoral system, then the public backlash could be withering.
Dishing the dirt on Key in the last week of the campaign may have seemed a clever move when the idea was first mooted within internet-Mana. It may yet be the the final humiliation for the parties of the left in an election campaign that has been turning into a disaster for them.
The timing was fortuitous for Key, but the news that Australia has raised its terror alert to the second-highest level would have sent more shudders down more spines than any filing cabinet full of the documents that Dotcom and the American journalist Glenn Greenwald may have.
It brings terrorism very close to home. It underlines the unwritten post-9/11 contract between the state and individuals.
That contract has the individual tolerating giving up some rights to privacy in return for -- to put it bluntly -- not being killed by a bomb blast in some airport somewhere.
Labour may be sitting on the fence when it comes to the future of the intelligence agencies. But it may prove to be far more comfortable than being stuck on Dotcom's side. Tonight, we will find out one way or the other.
