Mexico's democratic transition at the turn of the millennium was widely heralded as a decisive break with seven decades of one-party rule under the Institutional Revolutionary Party (PRI), yet more than two decades later, subnational elections continue to reveal the persistence of authoritarian-era structures beneath a competitive electoral surface. This tension sits at the heart of a new article in the Journal of Politics in Latin America, "Authoritarian Legacies and Incumbency Advantage in Mexico's Gubernatorial Elections: Party Machines Over Performance," published ahead of print in 2026. At a moment when scholars and policymakers across Latin America are debating whether formal democratization has genuinely dismantled clientelist governance structures or merely repackaged them, the article's focus on gubernatorial races offers a timely corrective to overly optimistic readings of Mexico's democratic consolidation. For an institute like IOCSS, which tracks how civil society and political accountability evolve in transitional democracies, the study's core question—what actually explains electoral success in Mexico's governorships since the transition—speaks directly to debates about whether decentralization strengthens or undermines democratic accountability in the developing world.

The article's central argument, as the abstract indicates, is that democratic competition after Mexico's transition did not simply reward or punish governors based on policy performance; rather, electoral outcomes were shaped by the interaction of democratic competition with decentralization and the residual strength of party machines inherited from the authoritarian period. In other words, the paper challenges a performance-based model of retrospective voting—the assumption that voters reward governors for good governance and punish them for poor outcomes—by showing that entrenched party organizational infrastructure, built up during decades of PRI dominance, continues to confer a durable incumbency advantage independent of actual gubernatorial performance. This is a significant empirical and theoretical move because it reframes gubernatorial elections not as referenda on policy delivery but as contests substantially determined by which party inherited and maintained the mobilizational apparatus of the old authoritarian regime. The implication is that Mexico's 32 state-level elections, despite operating under the same post-transition democratic rules, produce systematically different outcomes depending on each state's inherited party-machine legacy rather than on uniform standards of gubernatorial accountability.

This finding resonates with broader patterns observed across Latin America and other post-authoritarian polities, where decentralization reforms intended to deepen democracy have, in practice, often entrenched local power brokers and clientelist networks rather than dissolving them. Mexico's federalism, strengthened through fiscal and political decentralization since the 1990s, gave governors significant discretionary resources and patronage capacity, and the article's framing suggests that these decentralized powers became tools for sustaining party machines rather than mechanisms for localized democratic accountability. This pattern echoes similar findings in countries such as Argentina and Brazil, where subnational "authoritarian enclaves" persisted long after national democratization, sustained by provincial party organizations that controlled public employment, social program distribution, and local media access. For civil society researchers and ODA practitioners working on governance reform in Latin America, the Mexican case is a reminder that formal electoral competition—multiparty races, alternation in power, independent electoral institutions—does not automatically translate into programmatic, performance-based political accountability at the subnational level, where party machines inherited from authoritarian predecessors can retain an outsized role in shaping voter behavior.

The policy and research implications of this argument are considerable. For international donors and development agencies that have invested heavily in decentralization as a governance reform strategy—on the premise that bringing government closer to citizens improves accountability and service delivery—the Mexican gubernatorial evidence suggests a cautionary counter-narrative: decentralization can just as easily entrench legacy political networks as it can empower citizen oversight, particularly in contexts where one party dominated pre-transition state-building. This has direct relevance for ODA-funded governance and anti-corruption programming, which often assumes that electoral competition alone disciplines incumbents; the article implies that technical assistance focused narrowly on electoral administration or anti-fraud mechanisms may do little to address the deeper structural advantage conferred by inherited party infrastructure. Researchers studying democratic consolidation in other post-authoritarian contexts—including parts of East Asia and post-Soviet Eurasia, where IOCSS's comparative work on civil society often extends—may find the Mexican framework useful for distinguishing between formal democratic competition and substantive programmatic accountability, since the party-machine mechanism identified here is unlikely to be unique to Mexico's PRI legacy.

Looking forward, this study invites both practitioners and scholars to reconsider how success is measured in democratizing federal systems: electoral turnover and competitive races are necessary but insufficient indicators of healthy democratic accountability if the underlying mechanism of victory remains organizational inheritance rather than governance performance. Future research building on this Journal of Politics in Latin America article might usefully disaggregate which specific components of party machines—clientelist employment networks, control over conditional cash transfer distribution, or local media capture—carry the most weight in sustaining incumbency advantage, and whether newer parties such as MORENA, which displaced the PRI nationally in 2018, are beginning to reconstruct similar machine-based advantages at the state level. For IOCSS's broader research agenda on civil society and political economy, the Mexican case underscores that monitoring the quality of subnational democracy requires looking past headline indicators of party alternation and toward the organizational substrates—patronage networks, decentralized fiscal discretion, and inherited party infrastructure—that determine whether gubernatorial elections genuinely reward performance or merely reproduce authoritarian-era power structures under a democratic veneer.
