The Kentucky Derby is America’s oldest continuous sporting event. One of the more interesting pieces of Derby lore involves Richard Nixon.

Nixon was in attendance as a presidential candidate when Dancers Image crossed the line to win the 1968 Derby. However, a post-race urinalysis of the horse reveled traces of an anti-inflammatory drug that at the time was illegal at Churchill Downs.

The second-place horse Forward Pass was declared the winner. Thus Dancers Image became the only Derby winner to be disqualified on the same day that Nixon — the only American president to resign from office — attended his first Kentucky Derby.

The following year, Nixon returned to Churchill Downs, fulfilling a promise he made to attend the Derby if he won the presidency. Majestic Prince won the race without incident. To this day, Nixon is the only sitting president to attend the Derby.
