Hubert Humphrey was a Minnesotan who became a nationally prominent politician. He first ran for mayor of Minneapolis in 1943, but lost the election to the Republican candidate by just a few thousand votes.  As a Democrat, Humphrey recognized that his best chance for political success was to obtain the support of the Minnesota Farmer-Labor Party.  Other members of the Farmer-Labor Party had been considering the idea, as encouraged by Franklin D. Roosevelt, but the merger only became reality after Humphrey traveled to Washington, D.C. to discuss the issue.  Rather than simply absorbing the Farmer-Labor party, with its constituency of 200,000 voters, Humphrey suggested calling the party the Minnesota Democratic-Farmer-Labor Party.  He was elected mayor of Minneapolis in 1945, and one of his first actions was to propose an ordinance making racial discrimination by employers subject to a fine.  This ordinance was adopted in 1947, and although few fines were issued, the city's banks and department stores realized that public relations would improve by hiring blacks in increasing numbers. Humphrey delivered an impassioned speech at the 1948 Democratic National Convention encouraging the party to adopt a civil rights plank in their platform.  He was elected to the United States Senate in 1948 and was re-elected in 1954 and 1960.In the early 1960s, the topic of civil rights was coming to national prominence with sit-ins and marches organized by Martin Luther King Jr. and other black leaders.  In 1963, President John F. Kennedy sent a comprehensive civil rights bill to Congress, based largely on the ideas that Humphrey had been placing before the Senate for the previous fifteen years.  The bill passed the House in early 1964, but passage through the Senate was more difficult, due to southern segregationists who filibustered for 75 days.  Finally, in June 1964, the Civil Rights Act of 1964 became law.  Humphrey called this his greatest achievement. Lyndon B. Johnson recruited Humphrey for his running mate in the 1964 presidential election, and Humphrey became Vice President of the United States.  Governor Karl Rolvaag (DFL) appointed Walter Mondale to fill Humphrey's Senate seat.  Humphrey voiced doubts about the 1965 bombings of North Vietnam, which alienated him from Johnson.  He later defended Johnson's conduct of the Vietnam War, alienating himself from liberals, who were beginning to oppose the war around 1967.  In the 1968 presidential election, Humphrey ran against Richard Nixon and Independent candidate George Wallace and lost the popular vote by only 0.7%.  Humphrey later returned to the Senate in 1971 after Eugene McCarthy left office.Eugene McCarthy (DFL) served in the United States House of Representatives from 1949 through 1959 and in the United States Senate from 1959 through 1971.  He gained a reputation as an intellectual with strong convictions and integrity.  In 1967, he challenged Lyndon B. Johnson for the presidential nomination, running on an anti-war platform in contrast to Johnson's policies.  His strong support in the New Hampshire primary convinced Johnson to leave the race.Democrat Walter Mondale also achieved national prominence as Vice President under Jimmy Carter.  He served in the Senate from his appointment in 1964 until becoming Vice President in 1977.  In 1984, he ran for President of the United States, choosing Geraldine Ferraro as his running mate. The election proved to be a landslide victory for popular incumbent Ronald Reagan.  In 2002, just 11 days before election day, when incumbent Senator Paul Wellstone was killed in a plane crash, Mondale stepped into the race as the Democratic candidate for the U.S. Senate.  He lost the bid by two percentage points to the Republican, Norm Coleman.In 1970, Wendell Anderson (DFL) was elected as governor of Minnesota.  He spent two years working with a split Minnesota Legislature to enact a tax and school finance reform package that shifted the source of public education funding from local property taxes to state sales taxes, as well as adding excise taxes to liquor and cigarettes.  This achievement, dubbed the "Minnesota Miracle", was immensely popular.  In the next few years, the Legislature enacted other facets of their "new liberalism", including ratification of the Equal Rights Amendment, strong environmental laws, increases in workers' compensation and unemployment benefits, and elimination of income taxes for the working poor.  Time Magazine featured Wendell Anderson and the state in an article entitled, "Minnesota: A State That Works".  In 1976 when Mondale resigned his Senate seat to become Jimmy Carter's running mate, Anderson resigned the governor's seat and turned it over to Lieutenant Governor Rudy Perpich (DFL), who promptly appointed Anderson to fill Mondale's vacant Senate seat.  Voters turned Perpich and Anderson out of office in 1978, in an election dubbed the "Minnesota Massacre". Perpich was again elected as governor in 1983 and served until 1991.Paul Wellstone (DFL) was elected to the United States Senate in 1990, defeating incumbent Rudy Boschwitz (R) in one of the biggest election upsets of the decade.  In 1996, he defeated Boschwitz again in a rematch of the 1990 election.  Wellstone was known for being a liberal activist, as evidenced by his books How the Rural Poor Got Power: Narrative of a Grassroots Organizer, describing his work with the group Organization for a Better Rice County, and The Conscience of a Liberal: Reclaiming the Compassionate Agenda.  He explored a possible presidential bid in 1998, telling people he represented the "Democratic wing of the Democratic Party". On October 25, 2002, he was killed in a plane crash near Eveleth, Minnesota, along with his wife, his daughter, three campaign staffers, and the two pilots.Jesse Ventura, elected governor in 1998, had a colorful past as a Navy SEAL, a professional wrestler, an actor, mayor of Brooklyn Park, and a radio and TV broadcaster. He left office after one term.  His election brought international attention to the Independence Party.

Question: What is the full name of the person who defeated Boschwitz in a rematch of the 1990 election?
