gc_list_comments

Filter a rulemaking's comments

Slice one rulemaking's public-comment corpus: by stance (support/oppose/other), commenter type (trade_association, union, business, advocacy, government, academic, individual), campaign membership (a campaign id or "organic"), tagged issue, date range, or attachments. Organizations list first, then most recent. The flagship research tool — 'which trade associations oppose this rule' is one call. Campaign/issue filters are paid analytics.
