Former Prime Minister Turnbull went on to say:

… the government’s electoral woes, if that’s the right term, are a consequence of the decision made to change the leadership on the 24th of August.

"I mean, the polls—whether it’s the opinion polls or the [Victorian] election results—tell that story. It was … a destructive, mad, pointless exercise and the Australian people have been appalled by it."

Is Mr Turnbull correct?
