Here is a tweet from Delusional Donald on November 11, 2020.
Nobody wants to report that Pennsylvania and Michigan didn’t allow our Poll Watchers and/or Vote Observers to Watch or Observe. This is responsible for hundreds of thousands of votes that should not be allowed to count. Therefore, I easily win both states. Report the News!

Trump’s tweet superficially appears to follow the structure of assuming a premise which, if true, leads to a logical conclusion. He seems to think that the use of words like ‘therefore’ and ‘hereby’ give his tweets some logical and legal heft. But in this case, there is no evidence that the premise (that there exist hundreds of thousands of illegal ballots in Michigan and Pennsylvania) is true. Furthermore, even if it were true, the conclusion does not follow since it is possible that the majority of those illegal ballots were for Trump. If they were, eliminating them would make his margin of defeat even greater.
He needs another premise, that he somehow knows that the ballots that should not be counted had a majority for Biden that exceeded his final margin of victory, so that his argument goes:
Hundreds of thousands of votes were cast illegally in Pennsylvania and Michigan and should not be counted.
It was those votes that gave Biden his lead in both states.
Therefore, I win those states.
You would think a self-described stable genius would be able to construct a simple argument like that.
