Whitlam believed the Labor Party had little chance of being elected unless it could expand its appeal from the traditional working-class base to include the suburban middle class. He sought to shift control of the ALP from union officials to the parliamentary party, and hoped even rank-and-file party members could be given a voice in the conference. In 1968, controversy erupted within the party when the executive refused to seat new Tasmanian delegate Brian Harradine, a Whitlam supporter who was considered a right-wing extremist. Whitlam resigned the leadership, demanding a vote of confidence from caucus. He defeated Cairns for the leadership in an unexpectedly close 38–32 vote. Despite the vote, the executive refused to seat Harradine.
