Chris Selley says the New Democrats and Liberals should talk about a coalition before they talk about a merger.
… there’s very little standing in the way of such an arrangement except a little bit of leadership — legitimate coalitions cannot come from elections in which they’ve been explicitly disavowed — and, of course, an election result that makes it possible.
Both parties have much to do, if they’re to achieve such an outcome. But there’s no reason to believe they can’t do it separately and co-operate later, and plenty to like about having more choice in political parties rather than less. It would be a shame if one big idea was discounted in pursuit of another.
If memory serves, Jack Layton’s stance in the last election was that the NDP would work with any party in the House of Commons. If that position holds, the onus would seem to be on the Liberals to take a similarly open-minded position.
