This year marks the 150th anniversary of the Kentucky Derby. Nine U.S. presidents have attended the Derby, though only Richard Nixon did so while in office.

These facts seem to indicate both the abiding popularity of the race, but also that it was not a matter of political urgency or expediency for presidents to attend.

Kentucky Governor Earle Clements invited Harry Truman to the race in 1949, but the president took a rain check.

Although Truman recalled enjoying the race in his youth, he did not see it as something he had time for while governing.

While well attended across the centuries, horse racing has never been popular with all of the people all of the time, so it’s hard to gauge how much political capital a president might gain from association with the sport.

Though not constant, horse racing does have a longstanding connection with the presidency that can be traced all the way back to George Washington (1789–97).

Washington was a meticulous gambler who regularly attended race meets, and he was the first of many commanders-in-chief renowned for their love of the turf.

In the years that followed, Andrew Jackson (1829–37) retained a keen interest in racing as a presidential racehorse owner.

While Gerald Ford (1974–77) went to the Derby more than a dozen times, though not while occupying the Oval Office.

Racing proved valuable for Washington in that it afforded space for both pleasure and networking, both political and social, and this strategy worked for others as well.

Radio enabled Franklin Delano Roosevelt to benefit from the perception of an unparalleled solidarity with a racehorse in 1938.

Roosevelt’s engagement with a national sporting event was part of a larger effort to broadly support events that could raise people’s spirits in the Great Depression.

Richard Nixon went to the 1969 Kentucky Derby to meet with Southern governors and look like a man of the people.

Later in Nixon’s career he too helped raise spirits…mostly bourbon.
