I think Harper will pass a lot of laws trhat wer defeated previously by a slim margins. Ending the long gun registry for one.
I also expect to see incentives for businiess expansion in the feld of resource development, especuially oil and mining, as well as transortation subsidies for truck fuel and rail in certain industries.
Harper could also build some really big hydro electric dams in the North, in 5y ears the USA will need the power and the market for selling surplus power is very secure in the USA, since Obama is doing nothing about that except blowing smoke out if his a$$.
What about social policy, the oppression and criminalization of Christianity?
