How can the leftwing be split in Canada when there is only 1 leftwing party - the NDP. I'm looking forward to see the Tories and the Liberals split the rightwing vote!
If Ontario actually had close to a three-way split in the popular vote, I suspect that the seat distribution would be LETHAL for the Liberals. In would guess than in that scenario the NDP would sweep northern Ontario, the downtown and lower income parts of the GTA, the industrial towns of Hamiltonb, London, Windsor, Oshawa, Sarnia etc... the CPC would win all the rural seats and the more upper income parts of the GTA like York Region, Halton etc... and the Liberals could be left with almost nothing - what is their area of strength in Ontario? there is none
Parts of the GTA, especially higher income areas will never vote NDP, but aren't fans of the Tories either traditionally - in an election where they are weaker, the Liberals can take advantage of that.
