Did you read the article?
The author describes how section 5 is not relevant in the wake of voter fraud. The electors can be rejected based on illegal voting (as attested in Texas vs PA at al. and succinctly summarized by Navarro) forcing an Amend 12 solution.
We may also get a chance to see a VP candidate a shown to be ineligible.
I thought it also said that 2 through 5 only come into play if there is more than one set of electors. There is only one set in this case. I’ll have to read it again later when I am more awake.
