The point they are trying to make is if the ballots are fraudulent they wouldn't only vote for Biden and then vote for Republican Senators and Congressmen. If the election is going to be fully rigged you also take control of the senate and kick Mitch McConnell out. To a rig an election for just the president without control of legislature would make zero sense.

Well this is actually evidence for the fraud. It was posted in another tread. Biden's numbers were the only thing going up, while Trump and all of the down ballot stayed the same or only grew a little. Many ballots with nothing other than Biden marked. saves a lot of time and writers cramp.
