In 1968, who was the antiwar candidate for president?

In 1968, the antiwar candidate for president was Eugene McCarthy.

Explanation:

Eugene McCarthy was an American politician who had long been a member of the US Congress. He served in the House of Representatives from 1949 to 1959 and later in the Senate from 1959 to 1971. He was several times candidate to the presidency, without success.

McCarthy turned up against President Lyndon Johnson in the Democratic primary election in New Hampshire in 1968 to influence the federal government to push for the withdrawal of the Vietnam War. A large number of students and activists from across the country have come to New Hampshire to support McCarthy's campaign. With the publication of the results on March 12, McCarthy got 42% of votes and Johnson 49%. It was clear that there was a deep division in the Democratic electorate on the issue of war, and Johnson, convinced that he would not do unanimity in his own party, decided on 31 March not to run for re-election.

However, despite the good results in the primaries, McCarthy only collected 23% of the votes of the delegates at the 1968 Democratic National Convention, mainly because of the control of state organizations over the selection process of delegates, but also because of the entry of Robert Kennedy as an anti-war candidate. The party candidate was then Hubert Humphrey. As a result, the Democratic Party changed the rules for candidate selection, which were also followed by the Republicans.
