Media coverage of election-denying officials have greatly exaggerated how much impact individual refusals to certify can really have.

Remedies already exist and the mousetraps are already sprung (see @Aspenglow ’s post above). No one’s being caught off-guard this time around.
Further reading about the said remedies and certification safeguards in the post linked below.
