KeptSenate ProcedurePROMISE #1

Verdict reasoning

Independent voice / not beholden to party.

Verdict reasoning

Switched party affiliation to Independent in December 2022. Voted against key Democratic priorities including filibuster carve-out and broad spending packages. Maintained committee positions through Democratic caucus arrangement.

PartialHealthcarePROMISE #4

Lower healthcare and prescription drug costs.

IRA Medicare drug-pricing negotiation passed (Sinema YES) — but only after she negotiated for the removal of the 'pill penalty' clawback provision and changes to the negotiation timeline. Substantive drug-pricing reform delivered but at reduced scope from initial framework.
