Some dude on BBC, a statistician, says the SNP will inevitably win a majority of constituency seats...but many of Labour's constituency candidates aren't on the list. So a bunch of new Labour list MSPs on tap...
Makes no sense to me.
Scotland's voting system is essentially Mixed Member Proportional (MMP), where proportional lists are used to balance out disproportionate FPTP landslides.
Let's say a region has an overall vote of 40% SNP to 30% Labour. The region covers the same area as ten constituencies. The SNP wins every constituency, so the SNP sends 10 MSPs to Holyrood on the first vote. The SNP, however, has won such a disproportionate amount of seats that it will not gain any seats in the regional vote, even if it wins 40% of the vote there. Labour, winning 30% of the regional vote, gains 4 seats out of 7 available, because it received 50% of all the non-SNP votes.
Of course a Labour candidate running in a constituency can be placed on the list, but they can't be placed too high up - what if the candidate is eligible for both? Instead, they'll placed near the back end of the list, just in case. But Scottish Labour has even failed to do that, and when Labour gets its inevitable compensation you're going to see unknowns get elected, because the party never expected getting that many regional seats (or losing that many constituencies)
