A billionaire heir who campaigned on taxing his own family to win public office.

In short: Mark Dayton, scion of the retail dynasty behind Target, spent his career defying expectations. From his early days as a social worker to his tenure as Minnesota governor, he championed populist policies, famously promising to close tax loopholes for the wealthy—even if it meant targeting his own family’s fortune.

Born in 1947 into the family that founded the Dayton’s department store chain, Mark Dayton followed a path far removed from corporate boardrooms. After graduating from Yale, he worked in social services in New York and Boston. His political identity was forged in the 1960s and 70s, marked by anti-war activism that once led to him being maced by police during a protest against Honeywell, a company where his father served on the board.

Dayton’s political career was defined by a self-styled populist approach. During his 1982 Senate bid, he explicitly campaigned on closing tax loopholes for corporations and the rich, famously telling voters that if they thought his own family was included in that group, they were correct. Despite his wealth, he often relied on personal funds to fuel his campaigns, including a $12 million self-financed run for the Senate in 2000. His time in Washington was marked by unconventional moves, such as donating his salary to help seniors purchase prescription drugs in Canada and being the first senator to propose a cabinet-level Department of Peace.

As Minnesota’s 40th governor, serving from 2011 to 2019, Dayton navigated a complex political landscape. He was the first governor in the state to be inaugurated at age 64, and his administration saw significant legislative shifts. He oversaw the passage of laws allowing same-sex marriage and secured funding for the construction of U.S. Bank Stadium. His tenure was not without friction, including a government shutdown in 2011 and intense debates over tax increases on the wealthy. By the time he left office in 2019, having declined to seek a third term, he had established a legacy as a Democrat who consistently challenged the traditional boundaries of his party and his own privileged background.
