I think that if any election comes up they should give atleast 15 minutes of the debate dedicated to the issue of Afghanistan. Their are a number of ways to get that information out whether it be canvassing, townhalls, e-mails, etc.
The Liberals are being eaten into on both sides, people who are socially/morally/economically left of center, who also support the war have to grind their teeth and choose between politicians that are in line with their own political stripes and politicians who will help to do what needs to be done.
You just described me perfectly, left of center, however very few parties speak for me on that issue. If this was a direct democracy I would definitely vote in favour of the mission, but when an election comes I feel that I have to take into account all of the issues not just one with our current parliamentary system. You'll find that even in the NDP their are differences of opinion on Afghanistan, and some differences of opinion in the Liberal's. This is what we know for sure:
The NDP have been opposed to the mission since day on, and will remain opposed to the mission in the foreseeable future.
The Liberals originally supported the mission, then opposed the mission once new leadership came into play.
The Conservatives have always supported the mission, and will continue to do so as long as parliament permits.
The Bloc is opposed to the mission, more or less due to the fact their are high levels of dissaproval with the mission as compared to the rest of Canada.
The Green's are irrelevant at the time being until they get an MP elected.
I exempted the Bloc since they are not a nationwide party.
I think another reason why the Bloc is more outspoken now than before may be due to the byelections coming up. Currently their is apparently a tight byelection in a riding in Montreal where the NDP could come out on top. According to some poll's Jack Layton is considered the best federal leader by residents in Montreal. With Quebec provincially going back to divisions based on the right and the left with the Liberals [center left] taking government and ADQ [center right] the opposition, the Bloc is fearing they could start losing their social democratic/democratic socialist vote to the New Democrats, while the rural conservative vote will seep away to Harper in the next election.
