When a state legislator is prevented from running again due to term limits, the opposing party wins the seat 13 percent of the time. While such turnover may seem relatively modest, a Ballotpedia analysis found that it is twice as high as for non-term-limited seats.
The study analyzed 890 seats in 15 states held by a term-limited legislator from 2010 to 2011 and from 2013 to 2016. In 120 of those races (13 percent), the term-limited officials were replaced by an officeholder of a different political party.
Due to redistricting issues, the 2012 elections were not included in this study. See methodology.
Over the same time period, 19,642 non-term-limited state legislative seats were up for election. Of these non-term-limited seats, 1,329 seats, or roughly 7 percent, changed partisan control.
The following term-limited state legislative seats changed political party control from 2010-2011 and 2013-2016:
- 96 state legislative seats flipped from Democrat to Republican
- 20 state legislative seats flipped from Republican to Democrat
- Three state legislative seats flipped from Democrat to independent
- One state legislative seat flipped from independent to Republican
The following states demonstrated notable partisan shifts in term-limited state legislative districts from 2010-2011 and 2013-2016:
- In Arkansas, 22 state legislative seats flipped from Democrat to Republican.
- In Oklahoma, 14 state legislative seats flipped from Democrat to Republican.
- In Maine, 15 state legislative seats flipped from Democrat to Republican, 14 state legislative seats flipped from Republican to Democrat, and three state legislative seats flipped from Democrat to independent.
- In Montana, 13 state legislative seats flipped from Democrat to Republican while one state legislative seat flipped from Republican to Democrat.
- In Missouri, 10 state legislative seats flipped from Democrat to Republican while one state legislative seat flipped from Republican to Democrat.
- In Michigan, 10 state legislative seats flipped from Democrat to Republican while two state legislative seats flipped from Republican to Democrat.
