The courts have spoken. Trump appointed judges have ruled. There is no evidence of election fraud.
Hey Bonkers, do you even read your own link? No where in there do they claim there was no evidence. They didn't even spend the time (weeks) to even study and vet any of it. They simply ruled not to try the cases feeling an election is an election and it was better to leave it stand as it ended up rather than creating the turmoil of a court getting involved in possibly overturning one and being accused of then picking the POTUS instead and having to take all that political heat.
In the end, the courts decided that protecting the election itself was more important than addressing its correctness and veracity. They felt rightly that this is really a matter for the legislative body of the Congress to deal with.
