control of the party machinery by giving the nomination to Humphrey, who had been a loyal vice-president. Milne (2011) argues that, in terms of foreign-policy in the Vietnam War, Johnson at the end wanted Nixon to be president rather than Humphrey, since Johnson agreed with Nixon, rather than Humphrey, on the need to defend South Vietnam from communism. However, Johnson's telephone calls show that Johnson believed the Nixon camp was deliberately sabotaging the Paris peace talks. He told Humphrey, who refused to use allegations based on illegal wiretaps of a presidential candidate. Nixon himself called Johnson and denied the allegations. Dallek concludes that Nixon's advice to Saigon made no difference, and that Humphrey was so closely identified with Johnson's unpopular policies that no last-minute deal with Hanoi could have affected the election. Contest After Johnson's withdrawal, Vice President Hubert Humphrey announced his candidacy. Kennedy was successful in four state primaries (Indiana, Nebraska, South Dakota, and California), and McCarthy won six (Wisconsin, Pennsylvania, Massachusetts, Oregon, New Jersey, and Illinois). However, in primaries where they campaigned directly against one another, Kennedy won three primaries (Indiana, Nebraska, and California), and McCarthy won only one (Oregon). Humphrey did not compete in the primaries, leaving that job to favorite sons who were his surrogates, notably United States Senator George A. Smathers from Florida, United States Senator Stephen M. Young from Ohio, and Governor Roger D. Branigin of Indiana. Instead, Humphrey concentrated on winning the delegates in non-primary states, where party leaders such as Chicago Mayor Richard J. Daley controlled the delegate votes in their states. Kennedy defeated Branigin and McCarthy in the Indiana primary, and then defeated McCarthy in the Nebraska primary. However, McCarthy upset Kennedy in the Oregon primary. After Kennedy's defeat in Oregon, the California primary was seen as crucial to both Kennedy and McCarthy. McCarthy stumped the state's many colleges and universities, where he was treated as a hero for being the first presidential candidate to oppose the war. Kennedy campaigned in the ghettos and barrios of the state's larger cities, where he was mobbed by enthusiastic supporters. Kennedy and McCarthy engaged in a television debate a few days before the primary; it was generally considered a draw. On June 4, Kennedy narrowly defeated McCarthy in California, 46%–42%. However, McCarthy refused to withdraw from the race, and made it clear that he would contest Kennedy in the upcoming New York primary, where
