We're never going to get a majority. Not unless we can get Quebec. Because without a decent number of seats from Quebec, we would pretty much need to get 5/6 of all the other seats in Canada, which is impossible. We would need the Liberals to fall off the face of the earth and noone rise to take their place but us. So let's look pragmatically at how we're going to get a decent minority government and a good coalition.
The most likely members in a coalition are disgruntled Liberals who are mostly pro-life, pro-family and have strong reservations about Mr. Dithers (but were whipped into supporting some bills). It would likely take at least 140 Conservative MPs to allow them to put us over the top.
There is little chance that we will be able to find any common ground with the Bloc Quebecois or NDP.
