The Gibbard–Satterthwaite theorem, named after Allan Gibbard and Mark Satterthwaite, is a result about the deterministic voting systems that choose a single winner using only the preferences of the voters, where each voter ranks all candidates in order of preference.
Gibbard later covered the song "Choir Vandals" on Home Series Vol. V, a split EP with The American Analog Set's own Andrew Kenny.
Gibbard was born in Kaiapoi, New Zealand; he grew up in New Zealand and learnt his trade under the tutelage of Gordon Minhinnick (himself influenced by David Low), a former political cartoonist with the New Zealand Herald.
