It is very much about what Hitler came to power with, he tapped into the German resentment to the aftermath of the Treaty of Versailles (1919) which effectively ended WWI. It was only later that his evil intentions became known and by that time Germany had put him and his National Socialist German Workers Party (to become known as the Nazi Party) in power.
I think this is your mythical thinking. Most people in the UK were expecting a Biden victory based on the polls that were being issued which for weeks in advance and showed Biden ahead from between 7 to 13 percentage points. My point was about how anyone knew that the large slice of mailed-in votes were for Biden, before they were counted, how could they have known that? The answer that seems to have been accepted is that in some areas large parts of the Democratic vote stayed home and voted by mail, where as most Trump's people turned out to vote on the day.
