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 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.
