As usual Trump provides no evidence for this bullshit. He’s of course too stupid to even try to explain how this would work.
Just how would this work if election process is, by design, non-partisan?
They fill out mail in ballots to addresses they know no one lives or no record of voting, and they do so in the thousands, likely printing them up as we speak......send them in and then the day after the election they fight to get those ballots counted and snuck through the process....
They have their union thugs in the post office throw out and destroy mail in ballots from Republican majority voting districts.
We also had a thread on a democrat party fixer who detailed exactly how they cheat with mail in votes....you can look it up....
