Trudeau-hating Tories should be CHEERING Trudeau over this. Trudeau's just made a HUGE gift to Tories. Yes, this decision gives Liberals their best chance at gaining future majority gov'ts. But it simultaneously 
gives Tories THEIR best (or only) chance of majority gov'ts too. Trudeau apparently doesn't give a darn about that risk he's inviting. He'd rather "gamble" with Canada's 
future well being. 

Trudeau has now ensured Canadians will again have to risk  a right wing Harperite style gov't lording it over the 60%+ Canadian voters who vote left-leaning (Liberal + NDP + Green + Bloc). And if Canada ends up with its own extremist "PM Trump", we can "thank" first-past-the-post, and thank cynical & 
irresponsible Trudeau.

Harper will be smiling and raising a glass  to toast his new strange bedfellow ally, Justin Trudeau. 
Trudeau: Meet the new boss, same as the old boss?
