Actually this is about 2 parties that both lost, thinking that if they team up they can unseat the party that won the election.  They might be able to do so if they follow parliamentary tradition.  

Any break from that tradition and rules will upset our Westminster system of parliamentary government, and would give good cause for the Lieutenant Governor to doubt the suitability of the two-party amalgam to properly govern.  

The NDP need to respect the rules and traditions of the legislature.  Anything less and the LG is correct to call a re-election.
