Exercise 2: Why the SNP's Real Seats Don't Refute Duverger's Law — Possible Solution =========================================================================================== Political Theory Fundamentals' own Chapter 8 established Duverger's real mechanical effect precisely: a smaller party's real, total national vote share can win it zero seats if that support is spread thinly and evenly across many districts, while a smaller party with fewer total votes overall, but genuinely concentrated in a handful of districts, can win real seats there specifically. The law's own real prediction was never that FPTP prevents any third party from winning seats under any circumstances - only that FPTP structurally penalizes support that is spread out rather than concentrated. The chapter's own real, verified explanation shows the SNP fits precisely the concentrated-support case Duverger's own mechanical effect already predicts should succeed, not an exception to it. SNP support is genuinely concentrated within Scotland specifically, rather than spread thinly across the whole of the UK the way, for instance, a smaller UK-wide party's support might be. Because that support is geographically concentrated, the SNP can genuinely place first in a real, substantial number of individual Scottish constituencies, even though its own total UK-wide vote share, spread across the entire country, might be comparatively modest next to the two dominant national parties. This means the SNP's own real seats are, if anything, a genuine, concrete confirmation of Duverger's mechanical effect working exactly as the theory predicts - a party doesn't need to compete nationally to win real seats under FPTP; it needs its own support to be concentrated enough to place first within specific real districts, which is exactly the structural condition the SNP satisfies and a thinly-spread smaller party would not. ANSWER: The SNP's real Westminster seats don't refute Duverger's Law because the law's own mechanical effect specifically predicts that concentrated regional support, unlike thinly-spread national support, CAN win real seats under FPTP - the SNP's own support being concentrated within Scotland is exactly the condition under which Duverger's theory already predicts a smaller party can succeed, making this a genuine confirmation of the mechanism rather than a counterexample to it. WHY THIS WORKS AS AN ANSWER ------------------------------ This applies Political Theory Fundamentals' own specific real mechanical-effect distinction (concentrated vs. spread-out support) directly to the SNP case, showing the seats are predicted by the theory rather than contradicting it.
