There are 15 term limited states. Only Louisiana is not holding elections in 2010. Of the 14 term-limited states holding elections, 35.13% of all seats are open. In non-term limited states, that number plummets to 12.90%.
The discrepancy is largest in the Senate. In term limited states, 48.81% of seats are open. However, that number plummets to only 13.24% for states without term limits. That means 721 of the 831 Senators are running for re-election in states without term limits.
