Term-Limit Comparator

Analyze and Compare Term-Limit and Eligibility Architectures

Rotation Research’s Term-Limit Comparator is an interactive research tool for examining how eligibility rules govern time in office, time outside office, restoration, and recurring occupancy.

Preset coverage includes all 50 state legislatures and governorships, federal and historical architectures, and a maintained comparative dataset of local governing systems across the United States.

Start Here — Using the Comparator

1. Select one or two architectures. Choose a Featured Example, browse jurisdictions, or create a Custom Architecture. Analyze a single rule or use Architecture A and Architecture B to compare two rules or designs.

2. Examine the results. Review the available calculations and eligibility conditions. When comparing two architectures, use the Comparative View to examine their structural differences. Consult Legal provenance for the governing sources of preset architectures.

3. Understand the classifications. The Comparator applies Rotation Research’s taxonomy and classification framework. See Architectural Classification for the classification structure and Methodology for how Rotation Research conducts its analysis.

Interpretation of Comparator Results. Comparator presets are generated from Rotation Research’s maintained dataset and architecture classifications. Comparisons should preserve the governing unit, architecture type, service boundary, restoration mechanism, restoration interval where supplied, and any stated indeterminacy contained in the preset record. Generalized term-limit categories should not replace those classifications, and a fixed restoration interval should not be inferred where the governing architecture does not provide one.

What the Comparator Measures

The Comparator reconstructs each eligibility architecture using the temporal unit and restoration mechanism supplied by the governing rule.

Depending on the architecture, the comparison may include:

• Term Length (T): the duration of one ordinary authorization.

• Eligibility Boundary (S): the governing threshold at which eligibility for another authorization changes.

• Restoration Interval (R): where fixed by the rule, the minimum period outside the governed office or eligibility class before eligibility returns.

• Restoration Mechanism: the rule by which eligibility capacity returns.

• Restoration-to-Stint Ratio: required time outside office relative to the maximum permitted stint.

• Maximum Recurring Occupancy Share: the maximum share of a recurring stint-and-restoration cycle during which the same officeholder may occupy the office.

• Minimum Vacation Share: the minimum share of that recurring cycle reserved to interruption.

• Eligibility Restoration Point: where determinable, the earliest point at which renewed eligibility becomes available.

Comparing Term Limits Structurally

Two rules may share the same nominal service boundary while establishing different conditions for renewed eligibility.

For example, an eight-year stint followed by a two-year restoration interval permits renewed service after interruption. An eight-year lifetime limit terminates eligibility after exhaustion. A three-term limit also produces different service durations depending on the length of each term.

Structural comparison examines time in office and time out of office, together with the governing eligibility boundary, restoration mechanism, and eligibility endpoint.

Historical and Methodological Background

The Comparator was developed from Rotation Research’s study of the changing relationship between service, vacation, restoration, and renewed eligibility. Its historical baseline begins with James Harrington’s seventeenth-century architecture of equal rotation and equal vacations and follows the transformation of those mechanisms through later constitutional and modern term-limit systems.

Methodological Note

Comparator outputs describe architectural bounds, not predictions of actual tenure. Officeholders may leave before exhausting permitted service, remain outside office longer than required, decline renewed authorization, or fail to regain office after eligibility returns.

The analysis retains governing units and identifies indeterminacy where a rule does not establish a calculable restoration interval or other temporal measure.
