In 1974, Purcell was elected to the lieutenant governorship; he handily defeated Republican Leona Troxell of Rose Bud in White County, a former associate of the late Governor Winthrop Rockefeller. He was reelected as Arkansas Lieutenant Governor in 1976 and 1978 under David Pryor and Bill Clinton. He served as Acting Arkansas Governor for six days in 1979, having filled the unexpired term of Pryor, who had been elected to the United States Senate.[1]
Purcell was twice a candidate for the governorship. In 1970, he was considered the leading challenger to former governor Orval Faubus and ran second to Faubus throughout the primary race, but was edged out of a runoff berth by less than 500 votes by Charleston attorney Dale Bumpers, who went on to defeat Faubus and then Republican Governor Winthrop Rockefeller in the general election. Purcell was Bumpers' choice to chair the Arkansas Democratic Party, a position which he held from 1970 to 1973. His chief task as party chair was to purge followers of presidential candidate George Wallace of Alabama and former gubernatorial nominee James D. Johnson from the party ranks and to limit the influence of the Faubus-era "Old Guard" faction. He entered the Democratic gubernatorial primary in 1982 and surprisingly edged out former congressman Jim Guy Tucker for a runoff berth with former governor Bill Clinton. Purcell lost the Democratic nomination to Clinton in a runoff, 46 to 54 percent.[2]
