The FBI didn't interfere. And since Trump and Barr were in charge of the FBI, any "interference" would be on their poor leadership skills.
Trump didn't lose because people didn't hear about the laptop.
Trump lost because 400,000 people died of Covid, 65 million people lost their jobs or were laid off, and we had riots in the streets.
That's why Trump lost. By 8 million votes.
But lets say you get a court to hear cases that were previously rejected.
Here's the thing, there is no remedy for that.
There was no remedy if later recounts in Florida in 2000 found that Gore actually won.
There was no remedy in 1876 when electors were fraudulently awarded to Rutherford B. Hayes by a special commission.
There was no remedy in 1824 when Congress made a corrupt deal to make John Q. Adams president.
Here's a remedy. Get rid of the electoral college so any one state can't make mischief and throw an election.
