This timeline gathers dated cues from the retained Advance Colorado source cluster, especially the Who is Advance Colorado? microsite, linked tax-document PDFs, existing CTR reporting, and the newly captured $600k in 90 Days? article.
The timeline covers dated source evidence about Advance Colorado, linked nonprofit grant records, ballot-initiative activity, and the CTR-reported persuasion-network frame. It now includes bounded Title Board, TRACER, petition-entity, and West Group representative-role supplements, but it is still not a complete corporate, campaign-finance, or all-initiative chronology.
