In recent years, the comparative literature on presidential democracy has emphasised the role of coalitional politics in attenuating the ‘perils’ facing minority presidents. Yet since the beginning of the Third Wave of democratisation in 1974, a surprising number of minority presidents have eschewed cabinet coalitions (defined minimally as the awarding of at least one portfolio to a party other than the nominal party of the president). Unipartisan governments are observed just under half of the time. What explains the adoption of single‐party cabinets by minority presidents? Cross‐sectional time‐series analysis is employed to address this question. Hypotheses are tested that relate to the size and distribution of the formateur (presidential) and largest non‐formateur parties that make up the legislature; the nature of party linkages and ideological distance between the president and possible partisan allies; and the extent of reactive veto powers held by the president.
