I skipped through the speech after the first five minutes, stopping as points he held up charts and claims no one knows where the votes came from.
But we know, they came from high population counties that were pro-Biden. Or it was from mail-in votes, which were high this year. This is not new, or suspicious, or anything. He is just trying to stir up his base to keep them under his control to vote for him in four years.
This is one of the most un-Presidental things I have seen him done. Use the office to push conspiracy theories with little evidence. Just to keep a few voters on his side.
