The problem is that most serious people on the socio-economic and political 'left' are convinced, against all the evidence, that a socialist "workers' paradise" can be implemented, can be made to work if only intelligent, "right thinking" people, like themselves, are in charge. Most Bloqistes and Dippers are, in fact, decent, honest, well intentioned, albeit terribly naive, people who want what they are certain is best for us all. (In that they are fundamentally different from the 'left' wing of the Liberal Party which wants, above all, power for the Party and which hopes that some desirable socio-economic 'benefits' will trickle down to the masses.)
At a wild guesstimate, about one third of the public service falls into each of the categories of:
1. "serious people on the socio-economic and political 'left';" or
2. members of "the 'left' wing of the Liberal Party."
That means they are, fundamentally, opposed to the policies of the currently elected government. By the way, an equally wild quesstimate tells me that the media is more than half "serious people on the socio-economic and political 'left'." In other words, the media's bias is not pro-Liberal (if it is anything it is pro-NDP), it is, in the main just anti-Conservative because most (many? just some?) journalists really do try to hide their own, individual socio-economic preferences; they would never try to tell you to vote for the NDP but they cannot help suggesting that the Tories (and US Republicans) are evil incarnate.
