"Term limits would force out our best legislators."
It is true that term limits would remove some effective, experienced legislators from office. That is a real cost and should be acknowledged honestly. However, this argument assumes that the current system retains good legislators, when in fact it primarily retains incumbents — regardless of performance. The incumbency re-election rate in Congress exceeds 90%, meaning voters almost never remove anyone, effective or otherwise.
The average tenure in the US Senate is now over 11 years, and in the House over 8 years. Many members serve 20, 30, even 40+ years. This isn't because they're all exceptional — it's because incumbency advantages (name recognition, fundraising networks, gerrymandered districts) make them nearly impossible to defeat. Term limits would lose some good legislators, but they would also guarantee the removal of ineffective ones who survive on structural advantages alone.
Fifteen US states already have legislative term limits, and none have experienced a collapse in governance quality. In fact, studies from the National Conference of State Legislatures show that term-limited legislatures tend to be more demographically diverse, more responsive to constituents, and less dominated by party leadership. The 'best legislators' argument protects all incumbents, not just the good ones.
Structural advantages — not quality — explain retention
