Actually, the rise of the Alliance is an instructive lesson in the differences between the political/governing systems of Canada and the United States. The Alliance is, at its roots, a party that is founded in cynicism and frustration, the people of Western Canada feeling left out of government. Its parallel party in the US is the Reform Party, which arose here in the early 90’s out of the same sort of frustration and cynicism. But, whereas in Canada a third party can gain some national traction by obtaining enough seats in Parliament to do some serious heckling, requiring only that it have enough of a regional backing to win in some ridings, in the US, with its separate executive and with its winner-take-all Senate seats, third parties have much more difficulty obtaining a national presence. Further, the rapidly dwindling feeling of regionalism in the US makes regional factionalism even more unlikely.
In a further parallel, the Alliance has effectively been co-opted by a totally different political faction, just as the Reform Party got co-opted this year. But whereas Mr. Buchanan ejected the original message of the Reform Party, Mr. Day continues to embrace the basic philosophy of the Alliance (get federal government out of our provinces). In the United States, the ‘conservative’ (what I prefer to call orthodox) faction prefers to remain part of a traditional party, because in the US, the political mechanisms and structures make it very difficult for a third party to survive, even with as energized a base as you have on the ‘right-wing’.
As is usually the case with Parliamentary systems, the Liberals will maintain their pre-eminent position as long as the opposition remains fractured, and no national emergencies cause the people to rethink their affiliations.
One note regarding the post by Duke: While it is true that Ontario is important, your statement about how easy it is to win a majority in Parliament is inaccurate. Winning 51% of the popular vote in Ontario translates to nothing in particular. With multiple parties, it is conceivable that a party could bag ALL the seats from a province and win as little as 33% of the overall vote; a plurality is all that is required to send a member to Ottawa.
By the same token, it is equally possible for a party to win a strong majority of the overall vote, yet gain only half or fewer of the seats in a province. All it takes is close wins in several ridings, with large victories in the ones they win.
Ontario is a pretty diverse province, with everything from industrial to suburban to rural districts. Liberals have done well there of late because the Alliance preaches a message that doesn’t resound with the members of the province, and the other opposition parties have lost all their energy. But Ontario in the past hasn’t always been so solidly in one camp or the other, and yet, your thought about the ‘balance’ of the situation is, of course, exactly what energizes the Western Provinces into voting Alliance.
