Duverger's law

    • 2021 January 28, Michael Tomasky, “Why a Trump Third Party Would Be a Boon for Democrats”, in The New York Times‎, →ISSN:
      Out of that work emerged Duverger’s Law, which holds that single-member districts tend to produce two-party systems. […] And in the long run, the inexorable machinery of Duverger’s Law will ensure that the Patriot Party is folded back into the Republican Party.
