Voters across the Keystone State decided who will run their polling places in the next two elections, but you could forgive them if they didn’t realize it. Buried near the bottom of their ballots on November 2 were a pair of posts: judge of elections and inspector of elections, bureaucratic titles that most people have never heard of. In many counties, the contests didn’t even make the first page of local races, falling far beneath those for supreme-court justice, county executive, and the school board—even tax collector and constable merited higher placement.

Yet the people who hold these election positions will play an important—if often overlooked—role in determining whether elections in Pennsylvania go off smoothly. Grassroots Republican supporters of Trump’s efforts to overturn his 2020 defeat targeted these posts throughout the state, and many of them won their race last week. “There hasn’t been a sophisticated, concerted effort to sabotage elections like the one we’re facing now,” Scott Seeborg, the Pennsylvania state director for the nonpartisan group All Voting Is Local, told me.

For the next four years, judges and inspectors of elections will supervise polling places and ensure that votes are properly tabulated. Individually, they preside over a single precinct covering, at most, a few thousand ballots. But in the aggregate, the decisions made at such a hyperlocal level could tip close statewide or congressional elections, says Victoria Bassetti, a senior adviser to the nonpartisan States United Democracy Center. “It could add up, precinct after precinct after precinct,” Bassetti told me. Biased judges or inspectors might, directly or indirectly, skew a vote or two per precinct. “If people who are biased are elected to serve in these local positions anywhere in the country,” she said, “it ultimately could have a huge impact on how our democracy functions.”
