Nixon won Idaho by 22,744 votes, or 7.6%, which was significantly less than fellow Republican Dwight D. Eisenhower in 1956, who won the state by a margin of 22.4%, or 61,111 votes. This marked the first time since its admission to the union in 1890 that Idaho would back a losing Republican in a presidential election. This was also the first time since 1900 that the state failed to back the winning candidate in a presidential election. 4 years later, Democrat Lyndon B. Johnson would win the state by a margin of 1.83%, or 5,363 votes, which as of the 2020 presidential election, is the last time a Democratic presidential candidate has carried the state, or even broken 40% of the total vote. As of the 2020 presidential election, this is the last time a Democratic presidential candidate has lost Idaho by a single-digit margin.
