This is a routine primary campaign event where a candidate withdrew after a more prominent endorsement went to a competitor. Election driver scores 1.5 (minor primary influence, no systemic damage). Capture scores 1.0 (party influence dynamics). Mechanism modifier 0.6 reflects this is standard endorsement politics, not administrative manipulation. Scope 0.5 for single-state primary. Severity durability 0.8 (temporary campaign effect). Final A-score 0.54 indicates no meaningful constitutional damage. B-score 18.2 reflects moderate media interest in Trump-controls-GOP narrative but lacks viral elements. This is normal primary competition where endorsements matter - no institutional harm, no administrative interference, just political preference expression. Clear noise event.
