On November 4 , 1970 , shortly after being elected to the Senate , Humphrey stated his intention to take on the role of a " harmonizer " with the Democratic Party for the purpose of minimizing the possibility of potential presidential candidates within the party lambasting each other prior to deciding to run in the then-upcoming election , dismissing that he was an active candidate at that time . In December 1971 , Humphrey made his second trip to New Jersey in under a month , talking with a plurality of county leaders at the Robert Treat Hotel : " I told them I wanted their support . I said I 'd rather work with them than against them . " In 1972 , Humphrey once again ran for the Democratic nomination for president , announcing his candidacy on January 10 , 1972 during a twenty-minute speech in Philadelphia , Pennsylvania . At the time of the announcement , Humphrey said he was running on a platform of the removal of troops from Vietnam and a revitalization of the United States economy . He drew upon continuing support from organized labor and the African-American and Jewish communities , but remained unpopular with college students because of his association with the Vietnam War , even though he had altered his position in the years since his 1968 defeat . Humphrey initially planned to skip the primaries , as he had in 1968 . Even after he revised this strategy he still stayed out of New Hampshire , a decision that allowed McGovern to emerge as the leading challenger to Muskie in that state . Humphrey did win some primaries , including those in Ohio , Indiana and Pennsylvania , but was defeated by McGovern in several others , including the crucial California primary . Humphrey also was out-organized by McGovern in caucus states and was trailing in delegates at the 1972 Democratic National Convention in Miami Beach , Florida . His hopes rested on challenges to the credentials of some of the McGovern delegates . For example , the Humphrey forces argued that the winner-take-all rule for the California primary violated procedural reforms intended to produce a better reflection of the popular vote , the reason that the Illinois delegation was bounced . The effort failed , as several votes on delegate credentials went McGovern 's way , guaranteeing his victory
