Surely the more interesting conversation is trying to define / anticipate the shared elements (and prospective deal breakers) of an accord between the NDP and Liberals.
Reform of the electoral system... repeal (?) of c-51.... repeal of income splitting.... national child-care program ...???
It would be interesting, but I'm not so sure it's relevant here. Coalitions are about power. Policy is optional. Can you recall the shared platform elements of the Liberal-NDP-BQ attempted coalition of 2008 - other than preserving the parties' per-vote subsidy? Not saying there weren't any - just saying they escaped my radar. There was an agreement on who would be PM, how many cabinet seats and which ones, etc. But that's about power.
What I think would be an interesting conversation is trying to define what policies we would like to see a federal government enact - irrespective of which party or coalition comes to power. There has been little to none of that on this board, other than commenting on the occasional platform announcement (such as the ones you mentioned). But surely there is more to life than that?
