I was reading in the paper that a majority of Canadians who vote those parties think it might be a good idea to merge them in order to defeat Harper and the Conservatives. For me personally that would leave me no choice but to vote Conservative in the next election. If however the Conservatives really screwed up and that might force me into a different party that might appear because of the Conservative screw-ups.
The NDP has a lot of good ideas but for whatever reason can never come up a way to pay for them except to borrow money or tax the hell out of everyone in hopes that the money will come that way. Also when they are in power they will solve problems by doing nothing like leaving known crazy people on the streets to hurt others because they say they have a right to be there and shouldn't have to get treatment.
So to me if this merger happened it would be a terrible day for Canada and send us the the other half of the way to Greece.
