Republicans. Throughout the rest of the year, speculation about a potential Goldwater candidacy grew, and grass-roots activism and efforts among conservative Republicans expanded. Initially, Rockefeller was considered the front-runner, ahead of Goldwater. However, in 1963, two years after Rockefeller's divorce from his first wife, he married Margaretta "Happy" Murphy, who was nearly 18 years younger than he and had just divorced her husband and surrendered her four children to his custody. The fact that Murphy had suddenly divorced her husband before marrying Rockefeller led to rumors that Rockefeller had been having an extra-marital affair with her. This angered many social conservatives and female voters within the GOP, many of whom called Rockefeller a "wife stealer". After his re-marriage, Rockefeller's lead among Republicans lost 20 points overnight. Senator Prescott Bush of Connecticut, the father of President George H. W. Bush and grandfather of President George W. Bush, was among Rockefeller's critics on this issue: "Have we come to the point in our life as a nation where the governor of a great state — one who perhaps aspires to the nomination for president of the United States — can desert a good wife, mother of his grown children, divorce her, then persuade a young mother of four youngsters to abandon her husband and their four children and marry the governor?" In the first primary, in New Hampshire, both Rockefeller and Goldwater were considered to be the favorites, but the voters instead gave a surprising victory to the U.S. ambassador to South Vietnam, Henry Cabot Lodge Jr., Nixon's running mate in 1960 and a former Massachusetts senator. Lodge was a write-in candidate. He went on to win the Massachusetts and New Jersey primaries, before withdrawing his candidacy because he had finally decided he did not want the Republican nomination. Despite his defeat in New Hampshire, Goldwater pressed on, winning the Illinois, Texas, and Indiana primaries, with little opposition, and Nebraska's primary, after a stiff challenge from a draft-Nixon movement. Goldwater also won a number of state caucuses, and gathered even more delegates. Meanwhile, Nelson Rockefeller won the West Virginia and Oregon primaries against Goldwater, and William Scranton won in his home state of Pennsylvania. Both Rockefeller and Scranton also won several state caucuses, mostly in the Northeast. The final showdown between Goldwater and Rockefeller was in the California primary. In spite of the previous accusations regarding his marriage, Rockefeller led Goldwater in
