But there is far more precedent for a return to a divided right than there is for a merger of the centre-left, which has garnered much more ink in the last few years.
Certainly, the old Alliance and PC wings of the party are not as far apart now as the Liberals and New Democrats. The odds are that things will stay that way.
But a defeat in the next election may be far more disruptive than a simple change in government.
I've been preaching this for awhile. I think the future may be brighter than we think. Merging the NDP and the Liberals would be death to the left. It makes no sense. Like the split in the right the two parties are not natural bedfellows.
What we should be focused on is wiping out the Conservatives so that the Liberals and the NDP take the place of the two main parties of Canada. Merging the parties would be nuts even if it takes another couple of elections to achieve electoral dominance.
