Judge Comments on Candidate Support
During a sentencing hearing, Judge Harlan remarks that the defendant must have voted for the opposing party because of the neighborhood where he lives. Defense counsel objects and moves for recusal. The judge's comment triggers the rule against manifesting bias based on political affiliation in the performance of judicial duties.
Lawyer Attacks Witness Loyalty
In a contract dispute, attorney Ramirez cross-examines a witness by asking whether the witness belongs to the same political party as the plaintiff and therefore cannot be trusted. Opposing counsel objects that the question manifests bias on the basis of political affiliation. The presiding judge must require Ramirez to refrain from such conduct.

Campaign Finance Limits Upheld
A political party challenges contribution limits that treat coordinated expenditures differently from independent ones. The Court upholds the limits because they address the risk that large donations will create actual or apparent corruption tied to party affiliation. The decision turns on whether the restrictions are closely drawn to serve that interest.
McConnell v. Federal Election Commission540 U.S. 93, 226–27 (2003)
Disclosure Requirements Challenged
A minor political party objects to a statute requiring committees to report the party affiliation of supported candidates. The Court sustains the requirement because disclosure informs voters about the candidates' political ties and serves the interest in preventing corruption. The reporting obligation therefore survives exacting scrutiny.
Buckley v. Valeo424 U.S. 1, 93 (1976)
Judicial Candidate Speech Restriction
A state rule prohibits judicial candidates from announcing their views on disputed legal issues or identifying with a political party. The Court holds that the rule violates the First Amendment because it suppresses core political speech without a compelling justification narrowly tailored to preserving judicial impartiality.
Republican Party of Minnesota v. White536 U.S. 765, 122 S.Ct. 2528, 153 L.Ed.2d 694 (2002)
Primary Ballot Access Dispute
A state law requires candidates to be nominated by a party whose members constitute a certain percentage of registered voters. The Court upholds the law because it does not severely burden the associational rights of voters who wish to support a candidate of a different party affiliation. The restriction is therefore constitutional.
Washington State Grange v. Washington State Republican Party552 U.S. 442 (2008)
Common questions
Frequently Asked
3
Does the judicial conduct rule apply only to judges or also to lawyers appearing in court?+
The rule imposes an obligation on judges to refrain from manifesting bias based on political affiliation and separately requires judges to ensure that lawyers appearing before the court also refrain from such conduct. Both judges and lawyers are therefore covered when they act in judicial proceedings.

May a judge ever refer to a party's political affiliation during a proceeding?+
A judge may make a legitimate reference to political affiliation when the characteristic is relevant to an issue actually presented in the case. The rule does not bar every mention. It bars only manifestations of bias or prejudice.
Supporting sources
Does the First Amendment forbid all consideration of party affiliation in redistricting?+
No. Federal courts treat claims that a map was drawn predominantly on the basis of party affiliation as nonjusticiable political questions. Plaintiffs must show that race, not politics, was the predominant factor before strict scrutiny applies.
