Tucker was elected to the 51st Congress as a Democrat and served four terms. He thereupon returned to Washington and Lee, where he became the professor of constitutional law and equity in 1897. Three years later he was made Dean of the Law School, in 1900.
Tucker unsuccessfully sought the Democratic nomination for governor in 1909 and 1921. He returned to Congress in 1922, after a hiatus of nearly 25 years, when he was elected to the 67th Congress upon the death of Henry D. Flood in 1921. He was re-elected several times, serving until his own death in 1932.[2]
