It only falls when 156 members decide that its run it's course. If the CPC are smart (which I think they are at this point) they stick to working through their five points in order of ease:
1) Goverment Accountability - Easy support from the NDP and BQ. Libs will be shamed into supporting it too -- who wants to vote
against accountability afterall.
2) GST Cut - Swap out some corporate tax cuts and Layton will be onside. Fiscal liberals should be an OK sell too. Do it early too while no one in opposition wants to risk an immediate election.
3) Crime Bill - Likely sofened somewhat, but all parties talked about minimum sentencing.
4) Health Wait Times - As long as they stick to 'single public payer', this one passes, albeit with lots of negotiation.
5) Child Care Plan - Work a system where Quebec can maintain their provincial arrangement (asymetrical federalism, etc) with the $1200 flowing through the province, and you'll have the QB on side. They'll never turn down extra cash for Quebec when limited strings are attached.
6) For extra credit: Hold the SSM free vote (as a non 'non-confidence' motion),
knowing you'll lose it in al likelyhood, and with that put the issue to bed forever. I can dare to dream anyhow.
After that, begin to address the rest of the platform and see where consensis can be built. Don't ever be arrogant, work through the various multi-party committies, and remember its about the country, not the party alone. None of the opposition will pull the trigger if they're all working to the same goals.
Keep to that and you've got at least two years of legs on this one.
Or, maybe I'm a crazy CPC idealist. Who knows.
