Eisenhower: 40–50% 50–60%
The 1952 New Hampshire Republican presidential primary was held on March 11, 1952, in New Hampshire as one of the Republican Party's statewide nomination contests ahead of the 1952 United States presidential election. General Dwight D. Eisenhower defeated Senator Robert Taft of Ohio by 12 percentage points on his way to eventual nomination by the Republican Party for President and victory in the 1952 election against Democrat Adlai Stevenson. This was the first time that voters participating in the New Hampshire primary could vote directly for candidates, rather than for delegates to the Republican National Convention.
