In 1992, Billion was elected, along with fellow Democrat Linda Barker, as one of two South Dakota State Representatives from the Sioux Falls-based 13th District.[1] Billion was re-elected in 1994. In 1996, Billion declined to seek a third term in the State House, instead choosing to run for the State Senate from the 13th District. However, he lost to Republican Kermit Staggers by an 876-vote margin.[2] In 2006, Billion re-entered politics and emerged as the Democratic nominee for Governor of South Dakota in 2006. He selected Rapid City historian Eric Abrahamson as his running mate, but was overwhelmingly defeated in the general election by incumbent Republican Governor Mike Rounds.
