Year-to-Year Changes in State Partisan Control
In addition to the simple number of years each party was in control, we took into account the stability of the government’s partisan composition over time. We considered a partisan control change to have taken place when the partisan status of the legislature, governorship, or both changed. From 1992 to 2013, partisan control of each state government could have changed a maximum of 21 times.
State governments had 206 changes in party control, with an average of 9.8 changes annually nationwide. On average, the partisan status of each state’s government changed 4 times, approximately once every five years. Utah had the most stable government with no changes in its Republican trifecta control during this period. Idaho and Massachusetts each had only one change in party control. Nebraska, for which we were only able to track changes in partisan control of its governorship, also had one change. Wisconsin’s government had the most changes in partisan control with a total of nine changes. The Badger State’s party control changed nearly every two years. New Hampshire and North Carolina each had eight changes, followed by Colorado and Virginia with seven each.
