By Richard J. Heggen, University of New Mexico and Alfred G. Cuzán, University of West Florida

This article reports that an exponential survival model is a good fit for the reelection rate of the party that controls the executive office in states, territories, or provinces in three countries: Australia, Canada, and the United States.
