We all know that the winner-take-all system exaggerates regional differences in Canada, cheating Québec federalist voters, Alberta Liberal voters, and Toronto Conservative voters.
But it does the same in Saskatchewan, cheating rural NDP voters and urban Saskatchewan Party voters.
Today the ten MLAs from Yorkton-Melfort-Humboldt are all from the Saskatchewan Party. Although 27% of those voters voted NDP, they elected no representatives.
Of the 12 MLAs from Moose Jaw-Swift Current-Estevan-Kindersley, today 11 are from the SP, when a fair voting system would have let those voters elect three New Democrats and a Liberal.
This projection simplistically assume voters would have cast the same ballots they did in 2007. The reality would be different. When every vote counts, we typically see around 8% higher turnout.
However, taking those votes cast, with an open-list Mixed Member system the three regional NDP candidates in Yorkton-Melfort-Humboldt who got the most votes across the region would be elected (maybe Randy Goulden, Marlys Knezacek and Jordon Hillier.)
In Moose Jaw-Swift Current-Estevan-Kindersley, maybe NDP voters would have elected Glenn Hagel and Sharon Elliott or Ken Crush.
Note that, when the SP members from Moose Jaw-Swift Current-Estevan-Kindersley met in a regional nominating convention, they would have not only voted to put the eight local nominees on the regional ballot, but would have added several regional candidates. With only one or two women from the eight local ridings, when they nominated several additional regional candidates, they would have naturally wanted to nominate a diverse group: more women. And 90% of Canadian voters say that, if parties would nominate more women, they'd vote for them.
