Leader of Social Credit
Thorsteinson joined the Alberta Social Credit Party in 1991, and became leader the following year. Under Thorsteinson, Social Credit experienced the beginnings of a rebirth, and in the 1997 general election, the party nominated 70 candidates and collected 64,667 votes. This was Social Credit's best result since 1979, but it failed to win any seats in the Legislative Assembly of Alberta. By 1999, however, Thorsteinson, a convert to The Church of Jesus Christ of Latter-day Saints, was at odds with his party after a movement within the party to limit the involvement of Latter-day Saints. Thorsteinson quit the party in April 1999 and was a founder of the Alberta First Party but was not active in the party.
Leader of the Alberta Alliance

Later that year in the 2004 provincial election, Thorsteinson placed second in votes in his riding of Innisfail-Sylvan Lake, failing to become a Member of the Legislative Assembly. His party garnered 77,506 votes and won one seat in the election; Paul Hinman was elected MLA for the riding of Cardston-Taber-Warner. On March 7, 2005, Thorsteinson announced his resignation as leader of the Alberta Alliance, saying he would not be able to devote the time and energy into the party that was required of a leader. Paul Hinman, the lone Alliance MLA in the Legislature succeeded Thorsteinson as leader. Randy was elected as President of the Alberta Alliance at the 2007 Annual General Meeting held on March 24, 2007 in Edmonton Alberta. He had been serving a short stint as interim president of the party after former president John Murdoch stepped down. With the merger of the Alberta Alliance Party and the non registered Wildrose Party of Alberta on January 19, 2008, Thorsteinson declined to be a member of the new party and has had no involvement with the renamed Wildrose Alliance Party.
