Democratic operative In 1925, Biffle was appointed assistant secretary for Senate Democrats under Majority Leader
Joseph T. Robinson, who advised him to "keep your eyes and ears open and your damn mouth shut". He became majority secretary in 1933, managing "pair votes" to pass New Deal legislation and forging alliances with senators like
Harry S. Truman, whom he mentored upon Truman's Senate arrival in 1935.
Secretary of the Senate Biffle was unanimously elected Secretary of the Senate in 1945, a rare bipartisan endorsement. His tenure coincided with Truman's presidency, and the two maintained a direct phone line between Biffle's office and the White House. His back office, dubbed "Biff's Diner," became a hub for senators and lobbyists seeking Truman's ear.
1948 election and later work Biffle bolstered Truman’s underdog 1948 campaign by posing as a chicken farmer in a straw hat and truck to poll voters in the Midwest. His optimistic analysis proved accurate when Truman won re-election. Biffle retired in 1953 after Republicans regained the Senate but remained a consultant until his death in 1966. == See also ==
