No this is garbage. Nothing but unsubstantiated nonsense and speculation.

Zero credibility or evidence

The sad truth is, a lot of Americans voted for Trump and Biden waited far too long to stand down. I wouldn’t trust Elon Musk to hack an election but I would trust him to throw a stupid amount of cash at it.

Was there vote manipulation? Possibly, but a) I’d want to see some evidence and b) if it hadn’t been so close it wouldn’t have worked.
