Ballot Implementation
Following adoption of Initiative 1, Idaho election officials were authorized to implement ballot statements identifying candidates who declined to pledge support for congressional term limits.
Litigation History
Ballot informational statements concerning congressional candidates were later affected by the Supreme Court’s decision in Cook v. Gralike (2001), which addressed ballot labels favoring or disfavoring candidates based on policy positions in federal elections.
Relationship to Cook v. Gralike (2001)
The Supreme Court’s decision in Cook v. Gralike addressed ballot labels attached to congressional candidates based on policy positions.
Because Idaho’s Initiative 1 authorized ballot informational statements identifying candidates who declined to pledge support for term limits, the decision affected the broader legal viability of such ballot-label systems.
Institutional Design Observations
Idaho’s Initiative 1 represents a continuation of the pledge-and-ballot-information architecture that emerged following the 1996 instruction initiative wave.
The measure relied on candidate pledges and informational ballot statements to communicate positions regarding congressional term limits.
