The persistence of authoritarian institutional arrangements within formally democratic political systems represents one of the most consequential and underexamined phenomena in comparative politics. Across Latin America, the transitions from authoritarian rule that characterized the final decades of the twentieth century were celebrated as watershed moments — the establishment of competitive multiparty elections, constitutional reforms, and independent judiciaries that signaled the region's definitive turn toward liberal democratic governance. Yet decades after these transitions, scholars and practitioners alike have grown increasingly attentive to a troubling pattern: the formal architecture of democracy does not necessarily displace the informal networks, political machines, and incumbency advantages that were forged under prior authoritarian arrangements. Mexico offers one of the most instructive cases for understanding this disjunction, and recent scholarship examining gubernatorial elections in the post-transition era illuminates how legacy structures can shape electoral outcomes in ways that fundamentally complicate received narratives about democratic consolidation.

Mexico's transition away from the hegemonic rule of the Institutional Revolutionary Party (PRI) was long in coming and, when it finally arrived at the national level with Vicente Fox's victory in 2000, widely heralded as a definitive democratic breakthrough. Yet this framing obscures the deeply uneven character of political change across the country's thirty-one states and one federal entity. The research under consideration — published in the Journal of Politics in Latin America — interrogates the determinants of electoral success in gubernatorial contests in the period following democratic transition, asking a deceptively simple but analytically rich question: what explains why governors win or lose, and to what degree do sitting executives shape the electoral outcomes of their successors? The paper's central argument is that democratic competition, combined with the decentralization of political and fiscal authority to state-level actors, did not produce a politics of accountability anchored in government performance. Instead, it empowered party machines — organizational networks rooted in patronage, clientelism, and inherited political loyalties — that proved capable of delivering electoral victories independent of whether governors actually governed effectively. This finding carries profound implications not only for how we understand Mexican democracy but for broader theories of democratic consolidation and the resilience of authoritarian legacies.

The theoretical salience of this argument extends well beyond Mexico's specific historical circumstances. Comparative research on post-authoritarian democracies across Latin America, Sub-Saharan Africa, and Southeast Asia has consistently documented the phenomenon of machine politics and incumbency advantage operating beneath the surface of formal democratic procedures. The dominant paradigm in democratization scholarship long held that competitive elections, over time, would generate accountability pressures that incentivize performance — that voters would reward good governance and punish poor governance, thereby compelling politicians to deliver public goods rather than rely on the distribution of private benefits. The Mexican case challenges this optimism at the subnational level with particular force. Decentralization, which was understood in the 1990s and 2000s as a democratizing reform that would bring government closer to citizens and increase responsiveness, appears in this analysis to have had a more ambiguous effect: by concentrating resources and patronage networks in the hands of state-level political brokers, it may have entrenched machine politics rather than undermining it. This resonates with a broader scholarly literature that has increasingly recognized decentralization as a double-edged sword — capable of enhancing local accountability in some contexts while reinforcing elite capture and clientelistic exchange in others.

The policy implications of this analysis are substantial for international development actors, including the ODA community, whose programming in Mexico and across the region has long included democracy assistance, good governance initiatives, and institutional capacity-building at the subnational level. If incumbency advantage in gubernatorial elections derives primarily from party machine mobilization rather than from genuine performance differentials, then interventions focused narrowly on technical improvements to government service delivery may fail to shift the political incentive structures that govern how politicians relate to citizens. Electoral accountability requires not only competent government but also an informed, autonomous citizenry capable of evaluating performance and casting votes accordingly — conditions that patronage networks are specifically designed to undermine by binding voters to parties through material dependence rather than programmatic preference. Development practitioners investing in transparency mechanisms, civil society capacity, and electoral integrity programming must therefore grapple seriously with the organizational depth and historical rootedness of these machine structures, which cannot be dislodged through technical reform alone but require sustained attention to the political economies of clientelism at the local and regional scale.

Looking forward, this research makes a compelling case that students of Latin American politics and practitioners in the development field must resist the tendency to treat democratic transition as a singular event whose institutional consequences unfold cleanly over time. The Mexican experience suggests instead that authoritarian legacies are sticky — they embed themselves in party organizations, intergovernmental fiscal relations, and voter-party linkages in ways that outlast the formal dismantling of authoritarian rule. As Mexico continues to experience significant political realignment under the Morena movement and its successors, the question of whether new political actors will disrupt or reproduce these machine-based electoral logics remains urgently open. For researchers, this points toward the importance of granular subnational analysis that can capture the heterogeneity of democratic quality across states and municipalities — recognizing that aggregate national-level indicators of democratic health can mask profound local variation. For policymakers and civil society organizations, it underscores that durable democratic deepening in contexts like Mexico requires not only electoral competition but the transformation of the organizational and material foundations upon which political machines are built and sustained.
