There are many sworn affidavits being filed in court right now, from poll watchers claiming that they were kept too far away to validate a single ballot, or turned away entirely. We’ll see, it will definitely go to court.
Read the fact check. The too far away claim was decided days ago, and people were allowed to be within 6'. There were also live webcams setup. This has literally been one of the most transparent elections in history.
Read through the lawsuits [1]. Most have already been rejected due to no proof. The others outstanding have to do with so few votes it doesn't matter or they actually go against Trump's interests, like stopping the count when he's behind. This is all theater at this point. Maybe they can have a few more press conferences at the garden center next to the sex shop.
Note also the extremely telling detail that Trump's WinRed links for fundraising the recounts and legal challenges allocate 60% of those funds to retiring his campaign debt.
