We are seeing this in several places now.
The most effective fraud appears to have been in three steps:
1 - force the system to process enormous numbers of mail-in ballots, which are far harder to authenticate. This is done with Covid "emergency orders" and corrupt Secretaries of State, court cases, and physical threats by leftist brownshirts such as Antifa and BLM.
2 - Use the machines to put enormous numbers of ballots into adjudication, where the process is far less secure, and there are far more opportunities for political operators to change votes, overcount, or simply give the benefit of the doubt to Biden over Trump.
3. Use the people in the adjudication process to do the above, dump Trump votes or change them to Biden votes.
Antrim County, Michigan 68% ballots to adjudication. Adjudication logs wiped.
Clark County, Nevada (before the election) administrators said 70% of mail in ballots would go to adjudication!
Maricopa County, Arizona - Ballots which went to adjudication are supposed to have a serial number written on the original ballot and on the new ballot created to be counted. Many created ballots have a number, but the original ballots have not been found to match them.
And now, Windham, New Hampshire... The machines are unreliable with as many as 60% of the ballots in error.
It seems that 60% to 70% error rate keeps popping up.
Yes, it is called a repeating pattern of fraud.
Adjudication is the place you can launder ballots.
