One of the biggest things touted by the Trump supporters is the assembly of signed affidavits of people claiming to have spotted voting irregularities. They consider this to be evidence. However, as a comparison, look at all the people who claim to have seen extraterrestrial aliens. It's a very large number. If I count all those as strong evidence, then we can conclude that space aliens have been visiting us for a long while. It's not strong evidence, though. Every claim needs supporting evidence. Every person may be mistaken in their interpretation of what they saw, or outright lying, especially if they've already had a very strong bias towards their conclusion. Someone who believes there are aliens among us will be more prone to interpret all kinds of natural or man-made phenomena as alien in nature.
Someone who is strongly biased to believe that there's election fraud may mistakenly believe they've seen fraud. Some who wants Trump to win may perjure themselves if they think they can get away with it. And some may actually find cases of legitimate fraud. But until they have supporting evidence, all their affidavits are hearsay, which isn't going to go anywhere in court. Providing a list of affidavits is pointless without the supporting evidence. We've already seen a number of cases explained away with conflicting evidence, and quite a few lawsuits thrown out of court.
