What would change? Perhaps the future....
If Arizona looks at the numbers post audit and determines that due to fraud and illegally cast ballots that they don’t have confidence in their previous and decertify the election ......
It gives conservatives/election integrity folks a final “judgment” as proof to the mushy middle that fraud can change outcomes.
It’s well worth the effort.
To punish those who committed the fraud and take steps to keep it from being repeated? Definitely the effort is well worth it. One might say that it's vital. But the slate of electors is not going to be decertified. Biden is not going to be removed from office and replaced by Trump. People who think so are going to be disappointed.
