You can't assume the winner cheated just because they won - I don't think anyone's doing this; I know I'm certainly not. However, irregularities certainly need looking into.
Lastly, check your own bias - yes, yes, everyone has some kind of bias or another. I think we're all on the same page on this particular point, kinda goes without saying, TBH.
Want to call the election a fraud and a full recount whoever wins? - I'm not saying this. I'm just posting evidence for irregularities. Apparently, Trump is calling in a bolus of lawyers to look into this issue. I don't know where the situation goes from here.
Have you seen the first 8mins of the link I posted? What do you make of it?
