What does “completed” mean? Is the recount completed when the time allotted runs out, even if some counties are not finished, as was apparently the case with Florida in 2000? If “completed” means that all counties have reported, then any one county can nullify an entire state’s electoral votes.
"Completed" is under section (a), and I don't believe section (a) applies to presidential electors. They are addressed separately in section (b).
