Ugh. SK NDP wants to reduce the number of seats. So the next time the Sask Party gets 60%, they can be assured of getting wiped out entirely (save for maybe the two northern seats)
In practice, Saskatchewan is a bit gerrymandered with too many thinly populated rural ridings that are Sask Party strongholds. If the size of the leg were reduced from 61 to 55 seats it would mainly mean merging a lot of rural SP held seats while the under-represented cities (where the NDP seats are located) probably wouldn't change much.
You're thinking of 30 years ago. Since the Romanow government, Saskatchewan has used a +/-5% deviation limit--the lowest in the country. And there are just as many rural ridings above the provincial average as below (look up the 2012 provincial commission report). The only "thinly populated" rural riding in the province--Athabasca--is an NDP stronghold.
