The English is a bit more reserved than the French. The English states that it’ll be a victory party which just happens to be on election day whereas the French says that it’s a party of electoral victory!
I suppose victory is how you define it; the invite states that they are celebrating “the victory of our newly-elected Liberal Members of Parliament”.
The Toronto Star stated without irony (since that paper also endorsed the Liberals) that Stephane Dion may snatch the distinction of worst Liberal campaign ever from John Turner and his campaign performance in 1984.
However, as it goes, it’s a victory for democracy and all that… so while Conservatives will also be celebrating, we might just come over and buy a beer for some of our Liberal friends even if it’s going to be a Blue on election night.
