Initially a front runner for the Republican nomination for President of the United States in the 1968 election, he proved an ineffective campaigner and fell behind Richard Nixon in polls. After a mid-1967 remark that his earlier support for the Vietnam War had been due to a "brainwashing" by U.S. military and diplomatic officials in Vietnam, his campaign faltered even more and he withdrew from the contest in early 1968. After Nixon's election as president, he appointed Romney as Secretary of Housing and Urban Development. Romney's ambitious plans, which included housing production increases for the poor and open housing to desegregate suburbs, were modestly successful but often thwarted by Nixon. Romney left the administration at the start of Nixon's second term in 1973. Returning to private life, he advocated volunteerism and public service, and headed the National Center for Voluntary Action and its successor organizations from 1973 through 1991. He also served as a regional representative of the Twelve within his church.
