So, in addition to the objection above, that "they" would know which ballots to take so the voters wouldn't know, your "someone on the inside" would also need to know which ballots to take to be sure he was taking the right ones, i.e., Trump's and not Biden's. Unless you think he was just taking them at random and hoping for the best...
No, sorry, I think I'll stick with the verifiable facts.
ICYMI, ChrisBFRPKY explained part of that problem away by stating:
"Not if you targeted registered Republican voters. In that case you'd hear some complaints and allegations of fraud. You know, kinda like we're hearing now."
Can't you see that our intrepid leftist ballot thief network working for the USPS methodically removed 300k ballots of registered Republicans across multiple states and then carefully removed the ballots from the sealed envelopes, bleached out the mark next to Trumps name, marked it for Biden, resealed everything, and delivered them to the correct precinct. It couldn't be any simpler.
