Russell competed in the 1952 Democratic presidential primary, but was shut out of serious consideration by northern Democratic leaders who saw his support for segregation as untenable outside of the Jim Crow South. When Lyndon Johnson arrived in the Senate, he sought guidance from knowledgeable Senate aide Bobby Baker, who advised that all senators were "equal" but Russell was the most "equal"—meaning the most powerful. Johnson assiduously cultivated Russell through all of their joint Senate years and beyond. Russell's support for first-term senator Lyndon Johnson paved the way for Johnson to become Senate Majority Leader. Russell often dined at Johnson's house during their Senate days. However, their 20-year friendship came to an end during Johnson's presidency, in a fight over the Chief Justice nomination of Johnson's friend and Supreme Court justice Abe Fortas in 1968.
