Commmoner,

If the Alberta PCs & Wildrose merge but the merger lasts just long enough for a new but faction torn Party to become Government, then the divisions on social, fiscal and economic development Policy and the abandonment of the new Party  by disaffected members and MLAs will so discredit all concerned that 'the Right' in both its urban relatively moderate form & and in its social conservative uber free market suburban, small town & rural form will be discredited with the electorate.

If you think this scenario is a bit far-fetched, then ask your self whether the attempted merger of WildRose & the PCs under Prentice & Smith just before the last General Election didn't exhibit many weaknesses analogous to those I've just described and didn't fall apart and become discredited even more quickly that I'm now suggesting would be the case for a new merger attempt.
