Mexico's 2018 alternation of power and the subsequent consolidation of a new dominant party at the federal level have often overshadowed a quieter but equally consequential story unfolding in the country's thirty-two states: the persistence of subnational political machines that continue to shape who wins gubernatorial office regardless of formal democratization. As Latin America enters a period marked by democratic backsliding concerns, weakening party systems, and renewed debates over the durability of authoritarian-era institutions, understanding how legacies of one-party rule continue to structure electoral competition at the state level has taken on fresh urgency. Mexico, having transitioned from seven decades of PRI hegemony to competitive multiparty politics by 2000, offers one of the richest natural laboratories in the region for testing whether democratic institutions genuinely level the playing field or whether older patterns of clientelism and party infrastructure continue to determine outcomes beneath a democratic veneer. This is precisely the puzzle taken up by the article under review, which examines gubernatorial elections in the post-transition period to ask what actually explains electoral success at the state level, and how much credit or blame governors themselves deserve for their party's fortunes at the ballot box.

The article's central argument is that electoral outcomes in Mexico's gubernatorial races are driven less by the substantive performance of incumbent administrations than by the inherited strength of party machines that trace their organizational capacity back to the authoritarian period. Drawing on the logic of decentralization combined with democratic competition, the author contends that Mexico's post-2000 federalism did not simply create thirty-two independent laboratories of accountability politics, as much of the decentralization literature has optimistically assumed. Instead, it preserved and in some cases entrenched pre-existing party infrastructures, particularly those built by the PRI over decades of controlling patronage networks, local bureaucracies, and vote-mobilization structures. Where these machines remained intact, incumbent parties retained a durable electoral advantage that had comparatively little to do with whether governors delivered effective public services, managed public finances responsibly, or reduced insecurity. This is a notable departure from retrospective voting models common in comparative politics, which assume voters reward or punish incumbents based on observable governance outcomes. The article's findings suggest that in Mexico's subnational context, organizational legacy frequently trumps performance as the operative causal mechanism, a finding with significant implications for how scholars think about the quality of democratic accountability in transitional and hybrid political systems.

This finding resonates with and extends a broader body of research on subnational authoritarianism in Latin America, a literature most closely associated with scholars examining how national democratization can coexist with persistently undemocratic or semi-competitive enclaves at the state and municipal level. Mexico has long been a paradigmatic case for this phenomenon, with states like Oaxaca, Tabasco, and Coahuila frequently cited as examples of durable "hybrid" subnational regimes even after the PRI lost the presidency. What this article contributes is a more systematic, comparative account of the mechanism by which these legacies persist: not through overt electoral fraud or repression, which have become far less viable under Mexico's independent electoral institutions and robust monitoring apparatus, but through the mundane, difficult-to-observe advantages of organizational continuity — established local brokers, clientelistic networks, name recognition, and coordination capacity that opposition parties often cannot replicate even after decades of competitive elections. This pattern is not unique to Mexico. Similar dynamics have been documented in Argentina's provincial party machines, in Paraguay's Colorado Party strongholds, and in various regions of Brazil where historic political families retain outsized influence despite formal democratic competition. The article's Mexican case study therefore speaks to a broader regional pattern in which the transition from authoritarian to democratic rule at the national level does not automatically dismantle the organizational infrastructure of incumbent advantage, particularly in federal systems where subnational units retain substantial autonomy over patronage resources and where national parties lack strong mechanisms for enforcing internal accountability on their subnational branches.

The implications for policy and institutional design are significant. If incumbency advantage in Mexican gubernatorial races is driven primarily by inherited machine capacity rather than governance performance, then conventional accountability-enhancing reforms — greater transparency requirements, stronger audit institutions, freedom of information laws, or even competitive elections themselves — may be insufficient to produce the kind of responsive, performance-based democracy that decentralization reforms were originally designed to foster. This has direct relevance for international development actors and civil society organizations working on democratic governance and anti-corruption programming in Mexico and comparable contexts, since much of that programming is premised on the assumption that better information and stronger formal institutions will translate into electoral accountability. The findings suggest that donors and civil society groups interested in strengthening democratic quality at the subnational level may need to look beyond information and transparency interventions toward efforts that address the underlying asymmetries in party organizational capacity — for instance, supporting opposition party institutionalization, investing in independent local media that can substitute for clientelist information networks, or backing electoral administration reforms that specifically target vote-buying and patronage-based mobilization rather than only ballot-counting integrity. It also raises a cautionary note for how researchers and practitioners interpret electoral outcomes as signals of democratic health: an incumbent party's repeated victories should not be read uncritically as evidence of successful governance, nor should electoral turnover alone be treated as sufficient proof that meaningful accountability mechanisms are functioning.

Looking forward, this research invites further inquiry into how machine-based incumbency advantages evolve as Mexico's party system undergoes further realignment, particularly with Morena's rapid subnational expansion since 2018 raising the question of whether a new dominant-party machine is now being constructed using similar organizational logics, or whether its rise reflects a genuinely different, more programmatic mode of political mobilization. Comparative researchers working across Latin America and other regions with recent authoritarian pasts — including parts of Eastern Europe, Sub-Saharan Africa, and Southeast Asia — would do well to apply similar disaggregated, subnational analyses rather than relying solely on national-level democratization indices, which can mask considerable variation in the actual competitiveness and accountability of local politics. For practitioners in the ODA and civil society support space, the study is a reminder that democratic institution-building is rarely a one-time achievement following a national transition; it is an ongoing contest over organizational resources and political infrastructure that can take decades to genuinely level, and that requires sustained, locally calibrated support rather than one-size-fits-all governance interventions.
