I'm a computer programmer.
It's a trivial matter, maybe 4 or 5 lines of code, to tell a program to ignore, say every 10th or 15th Republican vote record.
Just loop through the input file, count 1,2,3, up to 10 records, throw away (ignore) that record, then continue.
As far as I know, there is no audit trail to compare the final count with the actual number of vote records submitted.
In Florida there’s an audit trail in that there are paper ballots that are bubbled-in and scanned. Those ballots are stored in a warehouse for 10 years. If they wanted to go back and manually count every one, they could; but they won’t.
