Groff was re-elected to a full term in 1976 and returned to the statehouse at each election up to his departure from the Colorado Senate. In 1976 Groff was selected by his Democratic peers as Assistant Minority Leader in the Colorado Senate.

During his time in the Colorado Senate Groff was instrumental in winning passage of legislation making the birthday of Martin Luther King into an official state holiday. He also worked actively in efforts to force the state to divest from investments in companies dealing with the Republic of South Africa, then ruled by a white minority government on the basis of racial apartheid. Groff traveled to South Africa, China, and a number of other countries in Europe and Africa on fact-finding missions and advancing the economic business of the state. In 1986 Groff unsuccessfully ran for statewide office in an effort to become Lieutenant Governor of Colorado.
