Scorched earth

Lawrence Martin thinks just about everybody is reaching their gag limit on the Harper Cons:

The strategy of the PMO has been to subjugate the other powers bases in Ottawa, the checks and balances in the system, to the point where they offer little resistance. The record shows that major progress has been made. But evidence suggests resistance is growing in many quarters, including, if opinion polls are to be believed, from the people themselves.

And the polls are also consistently showing the Trudeau Liberals beating the Harper Cons in the next election, irregardless of how many anti-Trudeau smears they run.
So basically Harper has another year as Prime Minister and then he will most likely be gone.
Will Harper go quietly into that good night? Or he is going to adopt the kind of "scorched earth" policies that will incinerate the country behind his retreat?
Do I even need to ask?
