The persistence of authoritarian legacies within formally democratic systems represents one of the most consequential and underexamined phenomena in comparative politics. Nowhere is this tension more instructive than in Latin America, where third-wave democratization reshaped constitutional orders and electoral rules without necessarily dismantling the organizational infrastructure through which entrenched parties had long governed. Mexico offers perhaps the most analytically rich case in this regard. The country's formal democratic transition — conventionally dated to the 2000 presidential election won by Vicente Fox of the National Action Party (PAN), ending over seven decades of Institutional Revolutionary Party (PRI) hegemony — masked profound continuities in how political competition was organized at the subnational level. A new article published in the Journal of Politics in Latin America engages directly with this puzzle, asking what explains electoral success in Mexico's gubernatorial elections following democratization, and to what degree governors themselves shaped those outcomes. The findings carry significant implications not only for students of Mexican politics, but for broader theoretical debates about democratic consolidation, decentralization, and the resilience of party machines in post-authoritarian settings.

The central argument advanced in this research positions party organization and machine-based mobilization — rather than gubernatorial performance — as the primary determinants of electoral success in subnational contests. This is a theoretically important claim because much of the prevailing literature on democratic accountability assumes that voters, once freed from coercive manipulation, will reward competent incumbents and punish underperformers. The performance-accountability model has been central to normative defenses of electoral democracy as a mechanism for improving governance. Yet the Mexican case complicates this narrative considerably. The combination of democratic competition and decentralization, which the article foregrounds as a structural condition, appears to have reinforced rather than eroded the organizational advantages of parties with deep roots in authoritarian-era governance. Governors operating within the legacy structures of the PRI — or parties that inherited those structures — retained enormous capacity to shape electoral outcomes through patronage networks, resource distribution, and party machine coordination, independently of whether their administrations delivered measurable improvements in public goods or economic welfare.

This finding resonates powerfully with a broader body of scholarship on subnational authoritarianism and the uneven geography of democratization in federal systems. Scholars such as Edward Gibson and Steven Levitsky have argued that national-level transitions to democracy can coexist with entrenched authoritarian enclaves at the provincial or state level, where incumbents exploit asymmetric information, resource asymmetries, and institutionalized patronage to maintain electoral dominance. In Mexico, decentralization transferred substantial fiscal resources and administrative authority to state governments during the 1990s and 2000s — a reform process intended in part to democratize governance by bringing it closer to citizens. Paradoxically, however, this devolution of power amplified the capacity of governors to deploy state resources for political purposes. The subnational arena became not a laboratory of democratic accountability, as optimistic reformers had hoped, but a competitive space where machine politics adapted and flourished. The article under review contributes empirical depth to this theoretical framework by systematically examining gubernatorial elections across multiple states and electoral cycles, providing evidence that incumbency advantage in Mexico is best explained by organizational infrastructure rather than policy outcomes.

The policy implications of these findings are considerable, particularly for international development actors and civil society organizations engaged in democracy promotion and governance reform in Latin America. Official development assistance targeting electoral integrity, institutional reform, and subnational governance has often proceeded on the assumption that strengthening formal rules — campaign finance regulations, independent electoral commissions, transparency requirements — is sufficient to produce meaningful accountability. The Mexican experience suggests that formal institutional reforms, while necessary, may be insufficient to overcome the organizational depth of machine parties that retain command over patronage flows and client networks. Efforts to improve gubernatorial accountability must therefore engage with the political economy of party organization itself, including the ways in which intergovernmental fiscal transfers can be captured for partisan mobilization. For multilateral donors and bilateral ODA programs working on governance, this implies a need to complement electoral reform initiatives with interventions that strengthen civil society monitoring capacity at the state level, support independent media, and reduce the dependency relationships that sustain machine politics. Without attention to the organizational substrates of political power, formal democratization may produce competitive elections that nonetheless reproduce authoritarian patterns of governance and accountability failure.

The article also invites reflection on the concept of incumbency advantage itself, which is frequently treated in the political science literature as a relatively neutral feature of democratic systems — a product of name recognition, resource advantages, and legislative experience. In post-authoritarian contexts, however, incumbency advantage is qualitatively different. It is not simply the advantage of being known or of having access to publicly funded media; it is the advantage of commanding an inherited organizational apparatus built over decades to convert state resources into electoral support. The distinction matters analytically because it suggests that incumbency advantage in these settings is not self-limiting in the way that scholars of consolidated democracies might expect. In systems where parties can use state office to deepen rather than merely exploit existing patronage networks, the feedback loop between electoral success and organizational capacity can become self-reinforcing across successive cycles, insulating incumbents from the accountability pressures that democratic theory predicts.

Looking forward, the research points toward several areas of significant scholarly and practical importance. As Mexico navigates a period of renewed political consolidation under the Morena movement and its successor formations, questions about whether the organizational logic of machine politics has been transcended or merely appropriated by a new political generation become increasingly urgent. The gubernatorial level remains critical, both because governors exercise substantial independent authority and because state-level electoral dynamics often anticipate and shape national outcomes. For researchers, the challenge will be to develop more granular measures of party organizational capacity and to trace the mechanisms through which organizational resources are converted into electoral outcomes across varied institutional environments. For practitioners in the ODA and civil society space, the lesson is perhaps sobering but clarifying: democratic consolidation in post-authoritarian federations requires sustained attention to the organizational underpinnings of political competition, not merely the formal architecture of electoral rules. The Mexican case, examined with the analytical rigor this article brings to bear, remains one of the most instructive in the world for understanding the long shadow that authoritarian legacies cast across democratic transitions.
