Political support is necessary but not always sufficient. A popular proposal can fail because a committee does not report it, a chamber cannot assemble the required votes, the president vetoes it, or lawmakers cannot agree on financing. Veto points can narrow a proposal as supporters bargain for a winning coalition. Conversely, an agency rule may be legally adopted without a congressional vote on the precise regulatory text because Congress previously delegated authority through a statute. Adoption therefore requires identifying both the approving institution and the procedure that makes its choice authoritative.

Suppose a bipartisan commission recommends replacing lead water lines. The report attracts praise and contains a detailed financing plan, but it is still a recommendation. If Congress later enacts an appropriation and authorizing rules, the legislative policy has been adopted. Agencies and states must then carry it out. The commission's report belongs to formulation; enactment is adoption; distributing grants and supervising construction are implementation. Public approval at a press conference is not a substitute for the legally required decision.

Adoption does not guarantee success, funding at the desired level, or faithful administration. It establishes what government has authorized, not what the policy will accomplish. For exam questions, ask: Who had power to approve this action? What procedure completed that approval? If the stem describes drafting alternatives, stay with formulation. If it describes rules, staffing, payments, inspections, or case-by-case decisions under an already approved policy, move to implementation.
