Final answer:
The slogan 'Not just peanuts' is not specifically mentioned in the historical records provided for presidential campaigns of the 20th century. Therefore, without additional context or information, its origin cannot be definitively attributed to any recognized presidential campaign up until the 2023 knowledge cutoff.
Step-by-step explanation:
The campaign slogan "Not just peanuts" does not directly relate to any listed presidential campaigns from historical records prior to the knowledge cutoff in 2023. It is likely that this slogan would belong to a campaign after the thorough records of slogans and strategies employed by the presidential candidates of the 1950s through the 1960s, as reported by the sources provided.
The provided resources discuss various historical strategies and slogans, such as Eisenhower's television commercials from the 1952 elections, Kennedy's slogans in the 1960 campaign, and even Lyndon Johnson's "The Daisy Girl" advertisement from 1964. Moreover, the slogan "Not just peanuts" could refer to a lesser-known or informal slogan not widely cited in academic references.
