Coalition Presidentialism in Bicameral Congresses: How does the Control of a Bicameral Majority Affect Coalition Survival?
Presidential legislative majorities under bicameral congresses have seldom been considered in the literature on coalition cabinets. However, this combination is far from being an isolated or irrelevant topic. Bicameral congresses comprise a double round of negotiation for the executive, increasing the shadow of the unexpected. Indeed, controlling one of the two chambers may not be sufficient for a president to guarantee the approval of policies. In this case, what if a government does not control both houses? How are coalition cabinets affected by the non-control of one or both chambers? I will focus analysis on the 25 cases of coalition cabinets in Latin America since the return of democracy and present a bicameral framework. Through mvQCA, I find that, contrary to common belief, the controlling of a bicameral majority is neither necessary nor sufficient to ensure stable coalitions.
