Senator Arnold Vinick (R-CA) (Alan Alda) secures the Republican nomination, defeating Glen Allen Walken (John Goodman) and the Reverend Don Butler (Don S. Davis), among others. Initially, Vinick wants Butler to become his running mate. However, Butler does not want to be considered because of Vinick's stance on abortion. Instead, West Virginia Governor Ray Sullivan (Brett Cullen) is chosen as Vinick's running mate. Vinick is portrayed throughout the sixth season as virtually unbeatable because of his popularity in California, a typically Democratic state, his moderate views, and his wide crossover appeal. Vinick, however, faces difficulty with the pro-life members of his party as a pro-choice candidate, and criticism for his support of nuclear power following a serious accident at a Californian nuclear power station.
