Your talking about a handful of cases.
I say the Republicans need to focus on all the ballets mailed out to every household.
The Democrats fill them out , bundle them and drive them to the vote counting rooms
The sleeve that has the signature on it gets removed and tossed, then the raw unidentified ballet gets into the vote pool, laundered
This is why you see 100,000 votes show up in the middle of the night in a van and all the votes are for one side.
They wait until they see how the vote is going and how many votes they need, then they place their order for late night delivery
Just like in Georgia. Trump was ahead like 380,000 votes with 2% left to count. Then, they stopped the count suddenly. It took them weeks to count the 2% and like 90% of them were for Biden? Some precincts, Trump got zero votes. And Democrats have the habit of finding a huge stash of uncounted ballots, the origin of which is not established but, they are counted just the same.
