When the electors meet and present their votes with seven states having conflicting sets of electors, it turns from an electoral issue to a Constitutional issue and all the Constitutional debates and stuff will then kick in demanding a Constitutional remedy. This is all designed so that one man does not have the final say.
The Constitution defines the VP as the person responsible to CONDUCT the election...
If there is no REAL controversy, that process tends to be fairly straightforward... as is true in other elections that are not corrupted by fraud. The VP conducts the election, and counts the votes by the process he, as the sole responsible authority, establishes. No controversy existing, means that process proceeds without ever requiring a controversy be resolved. When there IS a REAL controversy, as when fraud corrupts the results... and as when officials commit perjury by falsely certifying results... or when officials knowingly accept others fraudulent certifications without demanding corrections of frauds being practiced... that’s another issue.
The VP, is not absolved of his other obligations by his charge to be responsible for the PROPER conduct of the vote.
He ALSO has an obligation to ensure the laws are faithfully executed... and if he knowingly accepts the products of fraud in his official capacity, wherein he is required to reject the products of fraud... he should “be held accountable”... whether that means “go to jail” for simple malfeasance... or “be executed” for treason... depending only on the circumstances inherent in the instance ?
There are no competing electors. There is only one set of electors certified by those seven states and they are for Biden. The other “electors” are not certified and those votes won’t even be with the certified electors.
