The Pennsylvania gubernatorial election of 1954 was held on November 2. In what is considered a crucial realigning election for the state, Democratic State Senator George Leader defeated Republican incumbent Lieutenant Governor Lloyd Wood by a surprisingly large margin.
Entering the 1954 campaign, Democrats had a dismal record in state politics, winning the governorship only three times in 24 elections; the party’s stock had languished for fifteen years since the damaging administration of George Earle in the late 1930s. As a result, Leader was viewed as another mediocre if idealistic (he had gained some statewide recognition for refusing to sign a loyalty oath circulated in the legislature at the height of McCarthyism earlier in the year) Democratic candidate. However, Leader was embraced by the reform wing of the party, of which Leader’s father had been a member during his own tenure in the State Senate; a longstanding regional divide continued to haunt the Democrats in the their primary, as former Republican and vocal critic of organizational leadership Doc McClelland (the coroner of Allegheny County) gave Leader a strong run for the nomination. 
Republicans entered the race firmly unified behind Wood, but facing the deep unpopularity of their outgoing Governor Fine, whose administration had be embroiled in several scandals and who had led the push for a much criticized new sales tax. Furthermore, a huge rift had opened in the party between the middle class-backed progressive and big business-supported conservative wings of the party. A national recession, which pushed Pennsylvania’s unemployment rate to the highest in the nation also worked against Republican hopes of keeping their grasp on the governor’s mansion. 
After his close call in the primary, Leader ran an energetic campaign, travelling across the state and actively engaging citizens at rallies. In the first gubernatorial campaign where a significant portion of the population owned televisions, Leader ran a series of speeches where he captured audiences with his charismatic appearances; conversely, Lloyd appeared to sluggish in his campaign, and the media chastised his television appearances as “terrible.” Perhaps the most important factor in the race was Leader’s own principled character and his commitment for reducing the presence of patronage that had long given state government a bad name; for this attitude, he earned the nickname Mr. Clean. 
Leader performed not only well in the Democratic strongholds of Philadelphia, Pittsburgh, and Scranton, but won 34 of the state’s 67 counties. His impressive win included capturing victories in many GOP strongholds such as Bucks County (one of the heavily Republican suburban Philadelphia counties), winning over 60% in his home of York County, and becoming one of the only Democratic candidates for any major statewide office to take the state’s rural, conservative center.
