Not really ...
You know I'm not really one to be baited Tom.
That being said .... I don't think you maligned the NDP, I just think your assertion that they are all union and only union is far too limiting a description. In fact, Winston is correct (sometimes even Tories get it right!), they are more socialist and government oriented - as in social service/safety net/health programmes, human rights and labour protection issues, and corporate regulating. These are not necessarily things that unions support in all circumstances. Further, the NDP are also strongly oriented to public consultation and participation in policy development - far more voices and positions than just unions.
As a quick example, I cite the Employment Equity Act (now defunct thanks to Harris). Without going into the pros and cons of such a policy - it was quite intrusive into traditional and standard hiring, promotion, and retention practices. This is in direct conflict with Union positioning, yet the Act was still enacted and implementation had begun in ernest while they were still in their very short reign in Ontario.
I don't deny that their historical foundations may have been more directly associated with only unions, but that is clearly no longer their only focus or support base.
Keebler - ordinarily I would agree with you about voice appropriation, but Winston's answer was clear and concise. The question was about their differences, not their actual policies - which he properly identified fairly accurately without inflammatory detail.
I may have started it Tom, but my question has been answered to my satisfaction. This thread is done as far as I'm concerned.
Would you like to start a new thread discussing party policies in general? Its a pretty big can of worms, Pandora.
