How tech policy spreads, changes, and gets captured.
Technology policy in the U.S. is made state by state, but it doesn't originate state by state. Bills travel — borrowing text, weakening provisions, absorbing industry amendments, and arriving in the tenth state looking very different from the first. Propagate makes that process visible. It treats policy diffusion as an analytical object, not a background condition.
A tree/network diagram showing the lineage of bills within a policy family. Hover a node for a diff-style summary of what changed from parent to child.
Flag when a company that lost a policy fight in one state then registered to lobby on a similar bill in another state within 18 months.
Choropleth map of adoption status per policy family. Absence is data — 'no activity' states are analytically present with tooltip explanations.
Horizontal timeline of state introductions and passages, lag from first-mover calculated, velocity sparkline, and federal action milestones annotated.
Full dataset downloads: bills, positions, lobbying registrations, genealogy tags, timeline data, opposition salience field. Full codebook included.
This is not a bill tracker. Bill trackers show status. Propagate shows mechanism — who is driving adoption, how bills change as they travel from state to state, where industry advocacy is shaping outcomes, and whether visible opposition accelerates or slows diffusion. The primary audiences are policy researchers, investigative journalists, legislative staff, and public interest advocates.
