I dont doubt irregularities and illegalities but was it enough to throw the election?
I don't doubt it for a minute. I say that as a long time poll watcher and 'observer' of mail-in ballot counting in a swing state. Observer is in quotes because it was a partisan election operation in which observers weren't allowed to see anything meaningful. We could watch the scanning but not the intake. There was no ability to verify that ballots arrived in envelopes, with signatures, or postmarks. They could have come in little red wagons hot off the copier for all we knew.

All that was required to change the outcome was to rig the results in the toss up states. Watch the “2000 Mules” movie where ILLEGAL ballot harvesting by partisan NGO organizations paid harvesters to stuff many tens of thousands of ballots into “drop boxes”. IIRC, many more than the margins of victory in enough states to change the outcome.

Furthermore, in PA (a key swing state), unconstitutional changes in mail in voting laws were made prior to the election which heavily favored DemocRATS.

Before the election Joe was confident in the scope of the then to be election fraud, enough to brag about it.
