In 1952, when Senator Carl Hayden was 75, he hired 22-year-old Roy L. Elson as an assistant secretary on his Washington office staff. By age 27, Elson had become Hayden's administrative assistant. The aging senator found that the youthful staff member "thought his thoughts." Elson became the senator's surrogate in countless meetings involving the Central Arizona Project and other legislative issues. In 1962 he planned the senator's last campaign for reelection. As Hayden neared retirement, Elson himself ran as the Democratic candidate for the Senate from Arizona, in 1964 against Paul Fannin, and in 1968 against Barry Goldwater. He was one of the first Senate staff members to become a candidate. As Carl Hayden wrote in endorsement of Roy Elson's Senate candidacy, "Roy knows the Congress." In these interviews he shares that knowledge and experience, recalls his personal career, reflects on the senators and staff with whom he served, and offers a candid view of the legislative and appropriations processes. Roy L. Elson died in Sonoita, Arizona, on February 25, 2010.
