The fact that incorrect data is showing up on a national news station during the nation's most important election is pretty alarming. That is a cause for concern by itself. To make things more concerning they flipped into the other candidates favor.
To tell you the truth, I'm not so concerned with incorrect data showing up on news outlets. I take the news (w/r to an election) with a grain of salt). However, I am concerned with actual election results.
When the numbers flip into the other candidates favor that should raise alarms. Any number after that rightfully suspect.
If you are talking about down ballot issues, then yes, I am concerned. Anyway, we should seek accuracy for accuracy's sake, whatever the outcome.
Input errors are nothing new, it's only alarming to you because Trump lost, there are reports of errors undercounting Biden votes but you are not spreading twitter links telling everyone about it.
There's quite a few videos of things like this happening in different states. It's sad that they thought no one would notice. That's why they keep saying it's "unpatriotic" to question the results.
You need an investigation because no one is going to trust the vote in the future. Counting election results 5 days after the polls closed was idiotic and that's why Kavanaugh ruled how he did. He's obviously a smart guy. He wanted to ensure election integrity.
