Most of our socialist biases are due to complete apathy, ignorance or a justified hatred toward what they're told is "the right." People see Bush and Harper as "right-wing" and know that they disagree with that so assume they are "left-wing."
All we are taught about politics in school is that there is a linear political scale with communism on one side and facism on the other. If you are not one of two terrible people, Hitler or Stalin (whom we learn about extensively), then you are "somewhere in the middle." All of the "good" countries are from somewhere in the middle. All of the "bad" countries are from one or the other "extreme." The media tells us who is good or bad.
So all of the political parties fight off charges of extremism in an attempt to make sure no Canadians believe either party will move us "away from the middle." What results is thousands of bureaucrats having so few idelogical differences, that they are resolved to literally
defecating on each other to pass the time.
In order to ensure as little work as possible can be done in Ottawa (this may actually be a blessing in disguise) the political system gets periodically paralyzed by relatively frivolous issues or regulatory gaffes. The bureaucrats all point fingers at each other until the next calamity hits the news headlines and all is forgotten on the issue. 6 months later a law is passed creating a commission or an enquiry to the issue at hand. The findings are almost always "inconclusive" yet the new bureaucracy remains. In order to justify their new jobs' continued existence, they must cause some trouble that needs to be further investigated. (Images of gremlins scurrying around Ottawa, wreaking havoc always seem to come to mind.)
40% of Canadians see this charade for what it is and choose to metaphorically flip these bureaucrats the bird (and themselves in the process) by not voting. Another 6% of people vote for obscure parties, or Independants. Among the remaining 54% of voters, just under 20% elect the victorious party, with 50% of those voters choosing because they just "don't like the other guy." Essentially, 10-14% of Canadians vote for a party and a prime minister because they believe in both and trust both. This is the best form of democracy we could come up with.
In fact, it's not all that different from American politics. Which is precisely why there are so many Canadians interested in Ron Paul and his liberty movement.
