After losing in 1984, she became a fellow of the Institute of Politics at the John F. Kennedy School of Government at Harvard University until an unsuccessful bid for the U.S. Senate nomination in 1992.
She returned to the law after her 1992 Senate run, acting as an advocate for women raped during ethnic conflict in the former Yugoslavia.
Her advocacy work and support of President Bill Clinton won her the position of ambassador to the United Nations Human Rights Commission, where she served in 1994 and 1995.
She co-hosted CNN's "Crossfire," in 1996 and 1997 but left to take on Chuck Schumer, then a little-known Brooklyn congressman, in the 1998 Democratic Senate primary. She placed a distant second, declaring her political career finished after she took 26 percent of the vote to Schumer's 51 percent.
In June 1999, she announced that she was joining a Washington, D.C., area public relations firm to head a group advising clients on women's issues.
Ferraro revealed two years later that she had been diagnosed with blood cancer.
She once discussed blood cancer research before a Senate panel and said she hoped to live long enough "to attend the inauguration of the first woman president of the United States."
