Observed sources and real demographic data seed a modeled response. The output is synthetic—not observed polling, a forecast, or a statement of what the public believes.
Start with pending federal or state legislation, inspect its source and latest action, then estimate a synthetic public reaction. The separate Illustrative Lab lets you test invented legislative archetypes and interventions.
Read this first
Illustrative scenarios use real legislative archetypes, but none is before Congress and their sponsors are invented. Real Bills pulls pending legislation; its modeled public reaction does not forecast whether a bill will pass.

How this works
Congressional voting rules
Congress has real chamber, committee, scheduling, and voting rules that this lab does not model. Pheme shows only a synthetic-public response to illustrative bill text. It does not turn that response into fictional legislators, whip counts, or passage odds.
Political interventions
Shift voter opinions dynamically in real time: • Presidential Endorsement: Rallies the sponsor's party base but polarizes opposition. • Bipartisan Amendment: Shifts how cross-pressured synthetic groups respond to the revised bill text. • Ad Campaign: Shifts moderate and independent Census demographics. • Supreme Court Challenge Threat: Softens support among personas who see the bill as legally vulnerable, independent of its actual constitutional merits.
Modeled response & breakdowns
Voter Support: The percentage of the 50,000 synthetic voter profiles supporting the legislation. State Explorer: Shows state-level modeled support and direction. It contains no estimates of how real legislators would vote.
What's real here
Bill titles, chambers, sponsors, and latest action are pulled live from Congress.gov (federal, enriched with GovTrack sponsor/status) and Open States (state legislatures) — not illustrative. Simulate public reaction still runs Pheme's synthetic electorate against the bill's real text, the same engine behind Ask.
State coverage
State data comes from each legislature's own feed via Open States, so freshness and depth vary by state — a quiet state may show few or no recent bills even mid-session. We may have missed some. Federal coverage is complete for the current Congress.
Not a passage prediction
A bill still in committee hasn't been voted on — the reaction button estimates public support for its actual text (US nationally or for the selected state), the same way Ask does for any question. It is not a forecast of the real outcome.
State-level synthetic-public response only — no legislator votes or passage forecast.
