Input: Question: Who was the first person to hold the position Theodore Sorensen was nominated for? Passage 1:In the 1976 Republican primary, President Ford faced a challenge from former California Governor Ronald Reagan, who selected Richard Schweiker as his running mate. Though Thurmond backed Reagan's candidacy, he, along with North Carolina Senator Jesse Helms, led efforts to oust Schweiker from the ticket. During the subsequent general election, Thurmond appeared in a campaign commercial for incumbent U.S. President Gerald Ford in his race against Thurmond's fellow Southerner, former Georgia Governor Jimmy Carter. In the commercial, Thurmond said Ford (who was born in Nebraska and spent most of his life in Michigan) "sound[ed] more like a Southerner than Jimmy Carter". After President-elect Carter nominated Theodore C. Sorensen as his choice to become Director of the Central Intelligence Agency, Thurmond expressed reservations and fellow Senator Jake Garn said he believed Thurmond would not vote for the nomination. Sorensen withdrew from consideration days later, before a vote could be had.
 Passage 2:Although Hughes sang from a young age into adulthood in the choir of a Baptist church in her hometown of Dallas, she had no aspirations to be a professional singer and had been employed for five years as a nurse at Parkland Memorial Hospital in 1963 when an impromptu vocal performance at the local club where her close friend Tennyson Stephens played piano caused the club's managers to hire her. Established as a top local lounge act, Hughes and Stephens were eventually spotted in a Dallas club by Al Williams - leader of the Four Step Brothers dance troupe - who signed as the duo's manager successfully transferring them to the Chicago nightclub circuit. In 1965 Hughes made her recording debut with an album focused on standards - which billed Hughes as Rheta Hughes and featured Tennyson Stephens - entitled Introducing An Electrifying New Star recorded with producer Ralph Bass for Columbia Records, who would release three singles by Hughes in 1967-68 all produced by Howard Roberts (Hughes' Columbia recording sessions all took place in New York City). Continuing to play nightclubs, Hughes was discovered by Bill Cosby who caught her act at the Redd Foxx Club in Los Angeles, with Hughes resultantly being signed to Tetragrammaton Records, the label Cosby had recently co-founded. After her label debut: "You're Doing It With Her - When It Should Be Me", almost reached the R&B Top 40 in the autumn of 1968, Hughes scored her career record with a mid-tempo R&B rendition of the Doors hit "Light My Fire" which reached #36 on the Billboard R&B chart in February 1969 with the track just falling short of the Billboard Hot 100 peaking at #102 on the "Bubbling Under..." chart (Record World, whose R&B chart afforded Hughes' "Light My Fire" a #26 peak, ranked the track in its 100 Top Pops singles chart with a peak of #78).
