The Electoral Cycle and Institutional Sources of Divided Presidential Government

Presidents often lack legislative majorities, but situations of opposition-party majorities (“divided government”) are much less common outside the United States. The president's party's share of seats tends to increase in early-term elections but decline in later elections. Thus opposition majorities often result after midterm elections. Opposition majorities rarely occur in elections held concurrently with the presidential election but are more likely to do so if legislators enjoy electoral independence from their parties due to features of electoral laws.
