Assessments
Collins introduced and advocated for the bipartisan INSULIN Act in March-April 2026, which directly matched the promised $35 private/employer insulin cap and uninsured pilot program. However, the official bill record shows it was only introduced, read twice, and referred to committee, with no evidence of enactment or implementation. Because she made a serious legislative attempt but the promised policy outcome was not delivered, this is a failed promise with effort credit.
Senator Susan Collins introduced the INSULIN Act and led a bipartisan effort to cap insulin at $35/month for insured Americans, with a pilot for uninsured individuals. However, all evidence indicates the bill was introduced and endorsed but not enacted as law or implemented; thus, the policy promise was not delivered. Significant legislative effort was made.
Senator Collins co-introduced the INSULIN Act, which directly captures the campaign promise's elements: capping insulin at $35 for those with private and employer insurance and piloting the cost for the uninsured. However, all evidence describes only the introduction and promotion of the bill, with no information confirming it was enacted or that the policy is in force. Thus, the promise was not delivered, though substantial legislative effort is well-documented.
