100% it was his plan. His big plan has ALWAYS been to contest the validity of the election. He did it in 2016, talking for months up until he won about how it was going to be rigged and Hillary was gonna steal it, and how unfair it was to him. Then he won, and suddenly it's not rigged anymore! Now, he started the same thing again, months ago going on about how rigged the election was going to be, zeroing in on mail in ballots because they were inevitable, what with the pandemic. He doesn't know how to win if not to cheat, even when he legitimately wins.
