Democracy forces political elites to compete for power in elections, but it also often presses them to share power after the electoral dust has settled. At times these powersharing arrangements prove so encompassing as to make a mockery of putative partisan differences, and even to wipe out political opposition entirely by bringing every significant party into a "party cartel." Such promiscuous powersharing arrangements undermine representation by loosening parties’ commitments to their core constituents, and threaten accountability by limiting voters’ capacity to remove parties from power via the ballot box. In the otherwise deeply disparate cases of Indonesia and Bolivia, the origins of promiscuous powersharing can be traced to similar periods of high political uncertainty surrounding crisis-wracked transitions to democracy. Party elites coped with the uncertainties of transition and crisis by sharing executive power across the country’s most salient political cleavages. These arrangements forged an elitist equilibrium grounded in informal norms and networks, allowing collusive democracy to outlast the uncertain crisis conditions in which it was forged. Yet they have ultimately proven self-undermining by triggering distinctive popular backlashes, returning both countries to the political uncertainty that promiscuous powersharing was initially intended to alleviate.
