Impeachment and presidential politics in new democracies

Research on presidentialism has long assumed that presidential impeachment is a rare event, made difficult by design in order to enhance government stability. However, the experience of Third Wave democracies suggests that more presidents have been targets of impeachment attempts than the literature might lead us to expect. In this article I seek to identify the factors that make directly elected presidents more or less vulnerable to impeachment attempts in Third Wave presidential democracies from 1974 to 2003. I find several factors that mobilize deputies against the president: presidential involvement in political scandal, strong presidential powers, and a hostile civil society. Presidents are more likely to fend off such efforts when their party commands a higher share of seats. I also find that popular protest against a president helps to prompt a congressional impeachment drive. Frequent efforts to resolve presidential crises via such legal procedures may explain in part why extra-constitutional means of conflict resolution have become a less attractive option in new democracies.
