About Jack

​Santucci is a parties-and-elections scholar whose research has three threads: Using new analytic methods to revive and inform an old debate about the merits of single-transferable-vote elections in the United States; Answering practical questions about election administration so that policymakers considering reform can do so with more information; Analyzing change in the party coalitions, at the state and national levels alike, to better understand where our politics are going.

His dissertation analyzed the rise, fall, and effects of single-transferable-vote systems in 24 American cities, from 1893 to 1962. In the United States, the single transferable vote is commonly known as the ranked-choice form of proportional voting.

"Evidence of a Winning-Cohesion Tradeoff under Multi-Winner Ranked-Choice Voting" Electoral Studies (forthcoming).
