Biden's campaign manager said early on election eve that even if Trump took PA and FL there were other "pathways" to 270. That was the call to pull out all the stops, IMO.
Gen. McInerney said in the Bannon interview on 11/2 or 11/3 (not sure) that there would be a point where it looked like Trump was cruising but all of a sudden the roof would cave in. He said that they stopped that from happening in 2016, and the how and why he was not going to to divulge.
My take, then, is the steal was allowed to happen. The problem for the dems is now that, since Trump's vote total was so massive , the amount of votes necessary to overcome that spiraled into the absurd.
MSM telling everybody Biden won is based in the adage that it's easier to fool someone than it is to convince them they have been fooled. Meaning, to me, that the evidence of fraud is going to be so humiliating that more people will get pissed off at the dems then they will at Trump. Enough, at least, to make some type of national governance possible.
TLDR; planned sting to finally get the election bullshit cleaned out. Legllay, IANAL, but perhaps Trump had to allow himself to be subjected to criminal acts in order to achieve legal standing.
