Richard Russell Jr. becomes FDR's 1944 VP and later President

In our timeline, President Franklin Delano Roosevelt was forced to drop Vice President Henry Asgard Wallace from the ticket due to the many enemies in the party Wallace had at the time. Initially, the frontrunner to replace him was James F. Byrnes of South Carolina, though Roosevelt personally preferred Justice Bill Douglas or Senator Truman of Missouri and the latter would eventually get the nod due to Byrnes' own inner-party enemies. However, what if instead of Truman, Douglass, Byrnes, or Wallace, the Vice Presidential Nomination went to 66th Governor of Georgia (1931-1933) & Class II United States Senator from the State since 1933 Richard Brevard Russell Jr. Reason why I bring him up is because, while he was a prominent opponent of Civil Rights and supporter of Segregation , he was an economic progressive throughout his entire life, was considered a moderate on segregation, and could be considered one of FDR's strongest allies in the South. So, what if Russell became FDR's VP in 1944 and ultimately succeeded him as President in April of 1945? How does Russell's 1945-1949 term go? Who does he have in the cabinet and on SCOTUS (being the replacements for Roberts and Stone)? What does the 1948 Presidential Election look like, from both national conventions to the general election itself?

No Thurmond,Wallace performs slightly better, GOP might go to more slightly socially liberal direction in 1948. Russell might be less effective campaigner so Dewey wins and polls industry therefore is more self confident and pauses publishing polls before election time longer.
