Malcolm Turnbull rolled the dice. He won — but only just. The ambush worked — but only just.

Paul Keating, of course, took two attempts to blast Bob Hawke out of the top job. But that was early in the electoral cycle. A poll can be held any Saturday.

Now, the question is — will Turnbull roll the dice again, this time on a general election, in the hope he might fall over the line like he has this morning?
