rick,

All parties can do the mathematics. You may not agree with Weaver, who tried unsuccessfully to make a deal with the Liberals, but the man is clearly capable of doing integer arithmetic. If the Liberals wish to continue to govern then Clark has to appoint a speaker. If she does not do so soon the lieutenant governor may be forced to ask Horgan to try and form a government. An unstable government may clearly lead to another election in the near future, possibly with a similar outcome.
