1958 Pennsylvania gubernatorial election

Pennsylvania's branches of the two major parties entered the election in disparate states. Democrats were riding their largest wave of electoral success in nearly a century and quickly coalesced behind David L. Lawrence, the Mayor of Pittsburgh who had gained national fame as a reformer for his massive urban renewal projects earlier in the decade, but who retained a powerful traditional political machine Although Lawrence worried that his age (he was 69 at the time of the campaign) and his pious Catholic faith[4] may prove problematic, he was highly touted by party leaders . He easily defeated Lieutenant Governor Roy Furman in the primary after Governor Leader described Furman as unfit for higher office.[1]

Republicans, conversely, were just exiting a time in which their organization had gone through both electoral and financial disarray. The party had brought in McGonigle, a Reading businessman who had transformed Bachman Bakeries into the world's largest pretzel maker, to clean up their monetary problems. Although McGonigle had no intention of running for public office, his bookkeeping successes lead to many party bosses viewing him as a viable dark horse candidate.[1][5]

Lawrence entered the race as the clear favorite and ran on a platform emphasizing how the successes he had achieved in Pittsburgh, such as with environmentalism, economic development, race relations, and bureaucratic reform, could be applied to state government. He ran a generally quiet and issues-based campaign and grew frustrated with what he perceived as growing reactionary behavior from the opposing party. McGonigle’s campaign was more energized and continuously attacked Lawrence both for representing an archaic machine style of politics and for his position that the possibility of instituting a state income tax deserved study.[1]

Despite political winds that greatly favored Democrats in the national arena, the party's successes in the state were marginal. Lawrence’s campaign was never able to invigorate the base of urban voters and unionized workers in the manner that McGonigle did with key Republicans. A combination of Lawrence’s generally liberal viewpoints, powerful Appalachian anti-Catholicism[6] and contempt for his position as leader as a strong political machine undercut support in one of the greatest areas of Democratic support: the outlying industrial counties surrounding Pittsburgh's Allegheny County. Despite a generally disappointing vote total,[4] Lawrence was able to hang on to his frontrunner position to win the election.[1]
