No, not true. They are saying that this time they knew to watch close, so the Democrats couldn't pull of the same fraud as 2020. They are indeed stating that it is "supisious" that 13 Million Democratic voices where nowhere to be seen this time around, taking that as proof they were right all along.
That's how this works. You take reality and then make it mean what you want it to mean. So that's their take in regards to voter fraud.
Ah, so now it's time for baseless accusations from our side, yes?
As long as there is no proof this is as much a conspiration theory as the the bullshit the right was spewing about in 2020.
