You're absolutely right but there is one important rule that come into play here, the higher you are the less knowledge you need to have to do something (due you have your "specialists" at hand).

The second fact is that trump made him to the winner of the elections, how?
He told his voters to vote in person and NOT to vote by postal voting. His intention was clear (voting in person is more secure), but he took thousands of fake votes off his own party (as we all know, even dead people receive postal vote-papers)!

This produced the fake looking Biden"-Win" which was caused by postal voters inducing THEIR fake-votes by already dead people.
