The Draft Eisenhower movement reemerged in 1951 in both the Republican and Democratic parties, as Eisenhower had not yet announced any political party affiliation and believed that he needed to remain nonpartisan, citing Army regulation 600-10.18.i forbidding partisan political activity by serving officers. Democrats sought a candidate who could help them retain the White House after Truman, who many felt could not win re-election. Hoping that Eisenhower would run on behalf of the Democratic Party, Truman wrote to Eisenhower in December 1951, saying: "I wish you would let me know what you intend to do." Eisenhower responded: "I do not feel that I have any duty to seek a political nomination." Republican New York Governor Thomas E. Dewey and Senator Henry Cabot Lodge, Jr. of Massachusetts meanwhile worked to persuade him to run. Lodge began encouraging Eisenhower to run more than two years before the 1952 Republican National Convention, and Dewey on October 15, 1950, had announced his support for the general. Irving Berlin even included a song called "They Like Ike" in his Broadway Musical Call Me Madam, which opened in October 1950. Republican admirers coined the phrase "I like Ike" (referring to "Ike", Eisenhower's nickname) in the spring of 1951 as a symbol of their hopes. The "I Like Ike" slogan was created when Peter G. Peterson of Market Facts did research for the campaign and found out more people wanted to talk about how they trusted and felt comfortable with Ike, rather than describing their views on all the issues. Thus, "I Like Ike" went on all Ike paraphernalia.
