What's wrong with the Conservative party, what's holding them back? It's not the opposition but it may well be Stephen Harper. According to The Economist, Steve just isn't connecting with the Canadian people:
"Mr Harper has been unable to do much more than survive. Respected for his competence, he has all the charisma of an automaton. “I thought that people needed time to get used to Mr Harper,” says Roger Gibbins of the Canada West Foundation, an Alberta-based think-tank. “But it's turned out that to know Harper is not to love him.” That is especially true for women. Opinion polls show little change in allegiance since the last election—except for a brief moment of Conservative advance last autumn..."
I don't know about "respected for his competence," a claim that seems to be unravelling the longer Harpo remains in office but really "Automaton?" You gotta admit, I think that nails it right on the head.
