Tactical voting 2021: The basics
The SNP are a MINORITY party that wins because the anti-Nationalist opposition vote is split three ways. Of the 73 constituency seats in the Scottish Parliament Elections, 59 are currently held by the SNP. That’s an astonishing 81% of seats from just 46.5% of the vote.
Talk about not getting the government you vote for!
But how will tactical voting help? First we need to discard the two sets of seats where tactical voting won't make a difference. The first set is the 28 seats where the combined anti-Nationalist vote is still less than the SNP vote. Even if 100% of the anti-Nationalist vote swung to the second-place candidate, the seat would still remain in the hands of the SNP. In these seats the priority must be to increase the anti-Nationalist vote share.
