The promise's defining action is passing/advancing a balanced budget amendment (BBA) while protecting Social Security and Medicare. Since taking office (Jan 3, 2025), McCormick took no action toward the promised mechanism: he introduced no BBA and is not a cosponsor of the Senate BBA vehicle S.J.Res.97 (119th Cong.), a joint resolution proposing a balanced budget amendment sponsored by Husted with Lummis as cosponsor. An independent review of his record (Pennsylvania Independent) found he cosponsored 24 bills, and none would balance the budget. Meanwhile his signature fiscal vote, YES on the One Big Beautiful Bill Act (H.R.1), is projected by CBO to increase the deficit by about $3.3 trillion over the decade, cutting against getting the fiscal house in order (the bill did not directly cut SS/Medicare benefits, so that constraint was passively honored). Because he had a genuine available opportunity to advance a BBA and did nothing on it, the outcome is IGNORED. Confidence is moderate: it is early in a six-year term, a BBA is structurally near-impossible for any single senator to deliver, and he made one tangential restraint gesture (cosponsoring the non-binding S.Res.654) - but on the specific promised action his effort to date is zero, and his largest fiscal vote worsened the deficit.
