An Evolving Nomination Process
Presidential nominations are determined by who decides and who runs. Both factors are affected by the rules that structure the interaction of party constituencies and the candidates seeking the nomination. Rules impose constraints on participants and shape the incentives of both sides of the nomination equation-the politicians seeking the nomination and those seeking to influence the choice of nominee. Rules define who can participate in the selection process, which determines whose policy demands will be promoted by a political party. The rules also influence potential candidates when they decide whether or not to seek the nomination.
