I tend to agree that with the number of people that believe there was fraud in the election that it needs to be investigated. The problem is that no amount of proof will change anyone's mind. That is until President Trump himself will come out and say he lost in a fair election (if they are unable to prove any significant fraud). And I really don't think he is capable of admitting defeat. If there is fraud I really hope they can prove it.
If there is a big coverup I think it would have to be on a large scale and something that would be hard to detect. I don't think the reports of people showing up to vote and being told they had already voted by mail or observers being asked to watch from far away will really amount to anything. It would be near impossible to have widespread fraud with a lot of people involved. People like to talk and brag about things way too much for hundreds if not thousands of people to be in on something and for all of them to keep their mouth shut. But they need to look into everything none the less.
I haven't followed things as close as I probably should and I hope someone will correct me if I am wrong. But I believe the major part of the latest lawsuit is the fact that states improperly changed voting laws correct? So if for example the original law said my ballot had to be recieved by Nov. 3rd, and the state AG, Gov., or SOS changed it to where I'm told my vote only has to be postmarked by the end of the day Nov. 3rd. So in good faith I vote and turn in my ballot to the post office Nov. 3rd, now there is a chance my vote won't count. Right or wrong if that changed the outcome of the election I think that would give even more of the appearance of the election being stolen. I don't think we can change rules after the fact, even if they were illegally changed. I think we would have to re-vote in those states.
