Sanders was born on September 8, 1941, in Brooklyn, New York City. His father, Elias Ben Yehuda Sanders, was born on September 14, 1904, in Slopnice, Poland (then the Austro-Hungarian province of Galicia), to a Jewish family; in 1921, the 17-year-old Elias immigrated to the United States, where he became a paint salesman. His mother, Dorothy "Dora" Sanders (nee Glassberg), was born in New York City on October 2, 1912, to Jewish immigrant parents from Poland and Russia. Sanders became interested in politics at an early age: "A guy named Adolf Hitler won an election in 1932.

Sanders was a consistent critic of the Patriot Act. As a member of Congress, he voted against the original Patriot Act legislation. After its 357-to-66 passage in the House, Sanders sponsored and voted for several subsequent amendments and acts attempting to curtail its effects, and voted against each re-authorization. In June 2005, Sanders proposed an amendment to limit Patriot Act provisions that allow the government to obtain individuals' library and book-buying records. The amendment passed the House by a bipartisan majority, but was removed on November 4 of that year in House-Senate negotiations and never became law.  In March 2006, after a series of resolutions passed in various Vermont towns calling for him to bring articles of impeachment against George W. Bush, Sanders stated that it would be "impractical to talk about impeachment" with Republicans in control of the House and Senate. Still, Sanders made no secret of his opposition to the Bush Administration, which he regularly criticized for its cuts to social programs.  Sanders was a vocal critic of Federal Reserve Chair Alan Greenspan; in June 2003, during a question-and-answer discussion with the then-Chairman, Sanders told Greenspan that he was concerned that Greenspan was "way out of touch" and "that you see your major function in your position as the need to represent the wealthy and large corporations". In October 2008, after Sanders had been elected to the Senate, Greenspan admitted to Congress that his economic ideology regarding risky mortgage loans was flawed. In 1998, Sanders voted and advocated against rolling back the Glass-Steagall Legislation provisions that kept investment banks and commercial banks separate entities.
