Even though I lean to the right, I think it is best to have a mix of ideological governments.  Having all governments on the left or all on the right is not ideal, you need diversity as well as if you look at Canada's history there have been few if any points when all our governments have been on one side of the political spectrum.  The Saskatchewan Party may lose in 2020, but they still have plenty of time to recover.  In Manitoba it is a first term government so unless they mess up badly they will likely get a second term although no guarantee.  Never mind those don't happen until 2020 and I suspect of the Atlantic provinces, Quebec, Ontario, Alberta and maybe BC at least one will swing rightward.  The odds of every single election through 2021 producing left wing governments while possible is highly improbable, its basically like flipping 10 heads in a row.
