Despite strong showings in several primaries—he won more votes than any other Democratic candidate—McCarthy garnered only 23% of the delegates at the 1968 Democratic National Convention, largely due to the control of state-party organizations over the delegate-selection process. After Kennedy's assassination, many Kennedy delegates, remembering his bitter war of words with McCarthy, chose to support George McGovern rather than McCarthy. Moreover, although Humphrey was not clearly an antiwar candidate, some antiwar Democrats hoped that as president he might succeed where Johnson had failed and extricate the United States from Vietnam. Before election day, McCarthy confirmed that he would personally vote for Humphrey, but said that he would go no further than that, stopping short of endorsing him. Although McCarthy did not win the Democratic nomination, the antiwar "New Party", which ran several candidates for president that year, listed him as its nominee on the ballot in Arizona, where he received 2,751 votes. He also appeared on the Oregon ballot as the New Party choice. He received 20,721 votes as a write-in candidate in California.
