When was the last time the democratic nominee for president was not a descendent of slave owners?
As of my last knowledge update in October 2023, the last Democratic nominee for president who was not a descendant of slave owners was John F. Kennedy, who ran in 1960. Kennedy's family background does not include known slave ownership, while many other prominent Democratic nominees, such as Bill Clinton, Barack Obama, and Joe Biden, have familial ties to slave ownership. However, it's important to note that genealogical research can be complex, and new information may emerge over time.
