Early public service In 1949 Lowenstein worked as a special assistant on the staff of Senator
Frank Porter Graham and was a foreign policy assistant on Senator
Hubert H. Humphrey's staff in 1959. In the 1960s Lowenstein spent time in Mississippi as part of the
Freedom Summer, and an interview of Lowenstein was featured in episode 5 of the
Civil Rights Movement documentary
Eyes on the Prize.
South Africa and national politics In 1959, Lowenstein made a clandestine tour of
South-West Africa, now
Namibia. While he was there, he collected testimony against the
South African-controlled government (South-West Africa was a
United Nations Trust Territory). After his return, he spent a year promoting his findings to various student organizations and then wrote a book,
A Brutal Mandate, with an introduction by
Eleanor Roosevelt, with whom he had worked in 1957 at the
American Association for the United Nations. In 1960 Lowenstein was a delegate to the
Democratic National Convention.
Donald Rumsfeld. In 1966 he helped Senator
Robert F. Kennedy in writing his famous
Day of Affirmation Address, given to the
National Union of South African Students at the
University of Cape Town.
"Dump Johnson" movement and 1968 presidential race Along with
Curtis Gans in 1967, and later that fall joined by Wisconsin's
Midge Miller, Lowenstein started the
"Dump Johnson" movement, approaching Senators
Robert F. Kennedy and, at Kennedy's suggestion,
George McGovern about challenging President Johnson in the
1968 Democratic primaries. When Kennedy and McGovern both declined, Lowenstein, a delegate to the
Democratic National Convention, recruited and worked for
Eugene McCarthy, to whose
candidacy he remained loyal, even after Kennedy's late entry into the race (before Johnson bowed out). Johnson's withdrawal from the presidential nomination process has been attributed to the impact of the "Dump Johnson" movement, culminating in the historical precedent of McCarthy's strong showing against Johnson in the New Hampshire primary.
Election to Congress Lowenstein was elected to
Congress on
Long Island,
New York, in 1968 but was defeated in a modified district in 1970 by
New York State Senator Norman F. Lent by 9,300 votes, effectively
gerrymandered out of office by the Republican-controlled state legislature, which determined the district's boundaries.
Long Island's generally liberal
Five Towns region had been removed from the district, and the far more conservative
Massapequa added. Lowenstein captured 46% of the vote in the new district.
ADA leadership, "Dump Nixon" movement and Nixon Enemies List The 1970 election was viewed nationwide as a referendum on President Richard Nixon's conduct of the Vietnam War. In 1971, Lowenstein became head of the
Americans for Democratic Action and spearheaded the "Dump Nixon" movement, earning himself the number 7 spot on
Nixon's Enemies List.
Campaigns for Congress In 1972, Lowenstein ran unsuccessfully for Congress in
Brooklyn against Congressman
John J. Rooney, a
conservative Democrat supported by the party "machine," in the Democratic primary. After Rooney's victory was challenged and the election recalled due to allegations of fraud, Rooney narrowly won the rescheduled primary, but Lowenstein continued in the race on the
Liberal Party line, finishing with 28% of the vote. After an abortive 1974
U.S. Senate bid, Lowenstein unsuccessfully challenged incumbent Republican Congressman
John Wydler in a largely Republican district in Long Island in 1974 and 1976, receiving crucial support and endorsements from some local conservative Republicans as well as conservative
William F. Buckley, Jr. In 1974, he was defeated by Wydler, 58-42 percent.
Robert F. Kennedy assassination Lowenstein was one of the first public figures to cast doubt upon the official account of the June 6, 1968,
assassination of Senator Robert F. Kennedy. Lowenstein made a one-hour appearance on the PBS television show
Firing Line in 1975, where he was interviewed by
William F. Buckley Jr., in which he stated that he did not believe that
Sirhan Sirhan alone had shot Kennedy.
United Nations appointment and final campaign for Congress President Carter appointed Lowenstein as
United States Representative to the United Nations Commission on Human Rights, and thus head of the United States delegation to the thirty-third regular annual session of the
United Nations Commission on Human Rights in Geneva, Switzerland, in 1977. Lowenstein served with the rank of ambassador from August 1977 to June 1978 in the capacity of alternate United States Representative for Special Political Affairs to the United Nations. In 1978 he resigned his U.N. post to run for Congress in Manhattan's
"Silk Stocking District", narrowly losing the Democratic primary to
Carter Burden, who in turn lost the general election to Republican
S. William Green. ==Associations with conservatives==
