Wellstone had unseated the two-term senator Boschwitz in the 1990 election. Boschwitz filed for a rematch. He released ads calling Wellstone "embarrassingly liberal" and "Senator Welfare", and accused Wellstone of supporting flag burning, a move some believe backfired. As in 1990, Wellstone had a massive grassroots campaign that inspired college students, poor people and minorities to get involved in politics for the first time. Boschwitz significantly outspent Wellstone on campaign advertising and the race was closely contested, but Wellstone defeated Boschwitz by a nine-point margin in a three-way race. Dean Barkley received 7% of the vote and was appointed by Governor Jesse Ventura to serve the last few months of Wellstone's term after Wellstone died in a plane crash 11 days before the 2002 election.
