Legislation Owners
A bill's fate is decided by the people who own it. We track every Rapporteur assignment, Shadow Rapporteur appointment, and Committee composition change so you know exactly whose voting record dictates the outcome.
Worked example — Trading political ideology
The Green Transition Delay
When the EU's controversial Nature Restoration Law was suddenly reassigned to a conservative Rapporteur historically opposed to agricultural restrictions, the probability of the bill passing in its current form plummeted. By feeding our "Rapporteur Historical Voting Score" directly into their models, agricultural funds successfully shorted the compliance requirements months before the bill was formally diluted.
