Some proponents of the theory of American exceptionalism argue that this system and the accompanying distrust of concentrated power prevent the United States from suffering a "tyranny of the majority", are preservative of a free republican democracy, and also that it allows citizens to live in a locality whose laws reflect those voters' values.
Mõned Ameerika erandlikkuse teooria pooldajad väidavad, et see süsteem ja sellega kaasnev võimu kontsentreerumise umbusaldamine on USA-s ära hoidnud "enamuse türannia", säilitab vabariiklikku demokraatiat ja laseb kodanikel elada kohas, mille seadused peegeldavad sealsete elanike väärtuseid.
