Lol, it's not a lie. There's literally more than 100 news reports and articles about it and most would argue that ballot box stuffers are the enemies of democracy
Here you go bud, here's a video that shows the fraud taking place and that's just one short video they show. I watched all of the video on Epoch Time. A judge even ordered a redo in the election because of it. Video showed that 420 people put 1200+ ballots in the ballot boxes and this case has also caused lawmakers to write up a bill to increase election security in CT.
No need to appeal if this is true. The judge will more than likely have to declare a mistrial
