You're basing your conclusion that there was election fraud on 1 piece of information that wasn't included in the article.
I agree that Axios is pretty reliable as a reporting source.
But it could be an omission by the reporter (they didn't know to ask about it) or it could be something that isn't' required by state law.
That the sealing tape is only applied to the box once it is prepped to leave the voting center. I've read through a summary of AZ ballot law, and it doesn't say that the box has to be sealed up with special tape in the precinct, only that it has to be for transport.
But it's a summary, so I don't know.
However. I can infer that it's legal and proper because the RNC has done nothing to dispute those votes and have them thrown out. The RNC is staffed by people who are very experienced in election law, and if there was a chance to have ballots thrown out to favor their opponent, I would expect they'd do that at every opportunity.
Since they do exactly that in Texas.
We know that people who have a vested interest in Lake winning the election and have extensive experience in elections (and election law) don't see a legal opportunity to remove those ballots from the counting.
And that the precincts followed the correct process to collect the votes.
