An explanation as to why more people don't vote NDP

I often disagree with the guy on babble who calls himself Stockholm, but he does have a way with words, and in this thread he manages to frame the problem very well:

It's like if you asked 100 Canadians to name their favourite beer - 95% of them will automatically say Labatt's or Molson. Its only during an election campaign that they are forced to pay attention to Upper Canada and Sleeman's and be reminded that those brands actually taste a lot better than Labatt's or Molson.

That sounds about right to me, except for the part about noticing the good brands at election time.
