Endorsement Hesitation Weakens Kingmakers

When a dominant party figure delays or equivocates on endorsements in tightly contested primaries, local dynamics (vote‑splits, candidate quality, and turnout) can substantially blunt the endorsement’s power and make outcomes harder to predict. The Texas Cornyn–Paxton runoff shows that even a highly visible potential endorsement may not unify a fractured base or overcome candidate liabilities. — If endorsements no longer reliably decide primaries, party elites and outside actors must rethink intervention strategies and resource allocation in contests that can determine control of legislative bodies.
