The consensus on the AndrewCoyne.com blog appears to be about 130 seats for the Conservatives, 100 for the Liberals, 55 for the Bloc and 22 for the NDP and 1 IND. Canada will probably end up with a Conservative minority government. I think though, the results are wide open since the polls show a tie between the two major parties. Which way it could go today is any one's guess. One can make a few safe predictions an hour before the polls open in the East: the Conservatives will sweep Western Canada, the Bloc will take Quebec and Ontario will split right down the middle. Its going to be interesting night and if its down to the wire, we could be in for a long night when the polls close at the end of the day.
Isn't a minority government almost impossible to maintain? They can't (and won't) form a coalition with the other parties, so there will be a vote of no confidence the first time the liberals smell blood.
