At
The National Conference of State Legislatures, Karl Kurtz and Tim Storey write:
The combination of unusually high turnover in the membership of state legislatures after the 2010 election and anticipated high rates of churn after the redistricting election of 2012 makes it likely that approximately half of all state legislators will have served for two years or less at the start of 2013 legislaitve sessions. The 2010-12 cycle almost certainly will result in the highest rate of turnover in state legislatures over two elections in the last 50 years.
In a
more recent post, they add more data about states with and without term limits:
As term limits began to take effect and force legislators out of office in the mid-1990s, the gap between the two types of legislatures began to grow. By 2000, when term limit provisions had been enacted in 15 states, the gap was 19 percentage points (36 percent in TL states and 17 percent in NTL states), and the difference has remained consistently in the range of 15-20 points ever since.
