Each dot is a major political committee; a line joins two that pay the same vendors — the media firms, pollsters, mail houses, and consultants that run a campaign. Commodity vendors (Office Depot, the post office, Facebook) and contributions to candidates are filtered out, so a link means a shared operative, not a shared errand. Thicker, shorter links = higher overlap, weighted so a rare consultant outweighs a common one. Hover a node for a quick read; click a committee to isolate it and open its full shared-vendor sheet — every operative it shares, with whom.
