Federal override of state environmental policy creates significant constitutional damage through federalism violation (separation: 4.0) and represents regulatory capture by fossil fuel interests (capture: 3.5). The action directly undermines state sovereignty under the Clean Air Act waiver system, setting precedent for federal nullification of state climate policy. Election impact (3.5) reflects partisan positioning on climate/energy. Rule of law (3.0) reflects disruption of established regulatory framework. Civil rights (2.0) for environmental justice communities disproportionately affected by emissions. Mechanism modifier 1.15 for policy change with enforcement implications. Scope modifier 1.2 for federal action affecting largest state economy with national ripple effects. Severity: durability 1.1 (requires legislative reversal), reversibility 0.95 (policy can be reinstated), precedent 1.15 (establishes template for overriding state environmental authority). B-score elevated by culture war framing (outrage_bait: 7), media coverage of gas car bans (media_friendliness: 8), and strategic wedge issue deployment (narrative_pivot: 7, mismatch: 6). Intentionality moderate (8/15) for partisan timing and base mobilization. Delta +18.87 suggests Mixed classification as both constitutional damage and political theater are substantial, though A-score dominance indicates real federalism concerns.
