Bob Graham, a Florida Democrat who as a little-known state senator cleaned stables and waited on tables in a clever populist strategy that helped to boost him into the governorship, the United States Senate and a run for the presidency, has died. He was 87.

His daughter Gwen Graham posted a family statement on social media Tuesday evening announcing his death. The statement did not say where or when he died or provide a cause. Mr. Graham was disabled by a stroke in May 2020.

The son of a Florida state senator, Mr. Graham gained little political traction after 13 years in the State Legislature. He seemed destined to rise no higher than his father. Then he had an idea. Besides his official duties, he resolved to work eight hours a day in hundreds of mostly entry-level jobs to bond with his constituents. He performed what he called “Workdays” off and on for the rest of his career.

He was, for a day, a short-order cook, a bellhop, a social work aide, a plumber. He saw a murder victim on a night riding with cops. He was a department store Santa, a citrus packer and an office temp. He applied for food stamps. He picked tomatoes under a broiling sun, filled potholes, collected garbage, cut down tree limbs broken after a storm and was a circus clown.

Voters and the press, especially television news programs, loved these “Workdays,” which became a campaign staple. Mr. Graham would win two terms as governor (1979-1987), three terms in the Senate (1987-2005) and a heady but hopeless run for the White House in 2003.
