Benjamin Louis Cardin was born inBaltimore, Maryland.[2] The family name was originally "Kardonsky", before it was changed to "Cardin". Cardin's grandparents wereRussian Jewish immigrants. His maternal grandfather, Benjamin Green, operated a neighborhoodgrocery store that later turned into awholesalefood distribution company.[3] His mother Dora was a schoolteacher and his father,Meyer Cardin, served in theMaryland House of Delegates (1935–1937) and later sat on the Baltimore City Supreme Bench (1961–1977).[3][4][5]
Cardin and his family attended theModern OrthodoxBeth Tfiloh Congregation near their home, with which the family had been affiliated for three generations. Cardin attendedBaltimore City College, graduating in 1961. In 1964, he earned aBachelor of Arts degreecum laude from theUniversity of Pittsburgh,[2] where he was a member of thePi Lambda Phifraternity. He earned aJuris Doctor from theUniversity of Maryland School of Law in 1967, graduating first in his class.[2] Cardin wasadmitted to the Maryland Bar that same year, and joined the private practice of Rosen and Esterson until 1978.[2]
While still in law school, Cardin was elected to theMaryland House of Delegates in November 1966.[2][3] He held the seat once held by his uncle, Maurice Cardin, who had decided to not run for re-election so that his nephew could instead pursue the seat. He waschairman of theWays & Means Committee from 1974 to 1979, then served as the 103rdSpeaker of the House until he left office.[6] At age 35, he was the youngest Speaker in Maryland history at the time.[2] As Speaker, he was involved with reform efforts involving Maryland's property tax system, school financing formula, and ethical standards for elected officials.[6]
In 1986, with CongresswomanBarbara Mikulski mounting what would be a successful bid for the U.S. Senate seat vacated by retiring SenatorCharles Mathias, Cardin ran for Mikulski's seat in the3rd congressional district, which covered a large slice of inner Baltimore, as well as several close-in suburbs. Cardin won the Democratic nomination with 82 percent of the vote—the real contest in this heavily Democratic district. He won the general election with 79 percent of the vote against aperennial candidate,Republican Ross Z. Pierpont. He would be reelected nine times, dropping below 65 percent of the vote.
Cardin served as one of theHouse impeachment managers that successfully prosecuted the case in the 1989impeachment trial of JudgeWalter Nixon.[7]

Cardin has been commended for his work with fiscal policy. He has been honored byWorth magazine and byTreasury and Risk Management for his work protectingretirement plans and government-supported medical care for the elderly. He has also received scores of 100 percent from theLeague of Conservation Voters and theNAACP, indicating stances that are in favor of environmental protection andcivil rights.

On September 12, 2006, Cardin faced a challenging primary battle with other Maryland Democrats, includingAllan Lichtman,Josh Rales,Dennis F. Rasmussen, and his former House colleagueKweisi Mfume. Cardin won, however, with 44 percent of the vote, compared to 40 percent for Mfume, five percent for Rales, and two percent for Rasmussen.[10]

Cardin was participating in the certification of the2021 United States Electoral College vote count when theJanuary 6 United States Capitol attack happened. Cardin was on the Senate chamber floor when the rioters breached the Capitol. He was "ushered quickly — and I do mean quickly — away from the Capitol" after Vice PresidentMike Pence was removed from the chambers.[14] During the attack, while Cardin hid with other senators in a safe location, he tweeted, blaming PresidentDonald Trump for encouraging the rioters. He called for Trump to stop the protestors so the event would end "peacefully."[15] Cardin also compared the police involvement during the attack to that seen duringBlack Lives Matter protests, calling it a "stark contrast."[16] After the Capitol was secure, Cardin joined Congress to certify the count. After, he said that Trump should be held accountable for the insurrection and called for Republican leaders to tell Trump that he needs to resign.[17] Two days later, on January 8, Cardin called for the invocation of theTwenty-fifth Amendment to the United States Constitution or impeachment to remove Trump.[18]

The senators furthered that the FTC had the responsibility of protecting both consumers and workers and needed to "act decisively" to address their concerns over "serious anti-competitive harms from the proliferation of non-competes in the economy."[35]

The senators argued that foreign assistance to Central American countries created less migration to the U.S., citing the funding's helping to improve conditions in those countries.[75]
In 2023, Senator Cardin became the chair of theSenate Foreign Relations Committee.[76] According toJewish Insider, Cardin's office communicated to some activists that it does not have a plan to move theMahsa Amini Human rights and Security Accountability Act (MAHSA Act) forward through the committee, likely killing the bipartisan Iran sanctions bill.[77]

Thirty years after the end of the Cold War, it is time for democracies to band together and demand an end to the unprecedented corruption that has come to be the defining feature of the global order. We must purge the dirty money from our systems and deny kleptocrats safe haven."[83]
