Sounds crazy on both accounts. Either a record number of people voted for only one person or the fraudsters thought, “Eh, President is the only office we care about right?” I don’t know how they track votes but another key factor could be how dispersed the votes were. If it was fraud I’m guessing they’d be sloppy and you’d see the bullet voters show up in huge chunks.
That’s the most unrealistic part of this idea: Biden acting like Trump is a threat to the Constitution and not just another Republican.
