<P> The apportionment of seats in this House of Representatives was based on the Nineteenth Census of the United States in 1970 . Both chambers had a Democratic majority . It was the first time either party held a filibuster - proof 60 % super majority in both the Senate and House chambers since the 89th United States Congress in 1965 , and last time until the 111th United States Congress in 2009 . All three super majorities were Democratic party and also were accompanied by Democratic Presidents . As of 2018 , this is the most recent Congress to approve an amendment ( the unratified District of Columbia Voting Rights Amendment ) to the Constitution . </P>
