(Tuesday, March 12, 1968, polls closed at 8:00 .m. EST; during the Democratic Party presidential primaries, 1968, Republican Party presidential primaries, 1968 and during the Vietnam War) — President Lyndon Johnson barely edged out anti-war candidate U.S. Senator Eugene McCarthy of Minnesota today in the New Hampshire Democratic primary, the opening event in nominations for the 1968 U.S. presidential election.

Johnson, technically a write-in candidate, received 49.8% of the votes cast, but McCarthy, whose name was on the ballot, got 42.1% despite being relatively unknown outside of his home state.

The vote highlighted deep divisions in the country and the party over the Vietnam War and would demonstrate Johnson’s political vulnerability, prompting Senator Robert F. Kennedy of New York to join the race four days later on Mar. 16, 1968.

On the Republican side, former Vice President Richard Nixon overwhelmingly defeated a write-in effort by supporters of Governor Nelson Rockefeller of New York, winning 77.6% of the vote.
