Political Opinion & Affiliation

Detects references to political opinions and party affiliation: party membership, voter registration by party, political donations and campaign contributions. GDPR Article 9 lists political opinions as a special category of personal data with no fixed format — it is detectable only by topic vocabulary. Topic-grade detector, low confidence by design.

Confidence justification

Low by design. Political opinion is a GDPR Article 9 special category with no fixed format, so it is detected purely by topic vocabulary. Phrases like "voted for" appear constantly in non-political prose (awards, elections of officers, polls); pair with corroborative keywords (politics, election, candidate, donor) within the proximity window and treat single hits as low confidence.

Proximity: 300 characters

Should match

• CRM note records the donor as a registered Democrat in the swing district. — Registered Democrat term present
• The file lists each campaign contribution made during the election cycle. — Campaign contribution term present
• Profile field captures party membership and political affiliation. — Party membership / political affiliation terms present
• A political donation of record was flagged for the constituent. — Political donation term present

Should not match

• The quarterly sales report shows revenue grew across all regions. — Unrelated business prose, no political terms
• The committee registered the new vendor in the procurement system. — Near-miss prose ("registered" but not a party), no political opinion
• The team selected the winning design after a quick internal poll. — Unrelated prose, "poll" without political affiliation vocabulary

Known false positives

• Phrases like "voted for" or "registered" appear in non-political contexts (board elections, award votes, vendor registration), producing matches with no political-opinion content. Mitigation: Require corroborative keywords (election, candidate, donor, constituent, ballot) within the proximity window; treat isolated "voted for"/"registered" hits as low confidence.
