Actually it’s a two-step process for the RATS.
1. Voter Fraud While The Polls Are Open.
2. Voter Fraud During The Counting.
I thought the GOP pulled a uncharacteristically clever stunt during the WI assembly elections a couple years ago. They held a heavily pro-GOP precinct's locked ballot boxes until all the other votes had been collected and counting was underway. Then they produced them.
The democrats didn't know how many ballots to manufacture, and were defeated in key races.
