What you expose is the methods. The Democrats have created ways to ensure the number of votes they get. in 2016, they felt they didn't need them to beat Trump. This was Hillary's coronation. In 2020, they pulled out all stops to beat Trump and they got sloppy. They exposed the methods. Like the Mafia, this is a vast financial empire. Growing up in a Southern city, I learned how it worked. The highest voting precincts were in the poorest neighborhoods. Most precincts were 40% but they were 92%. I voted in one of them in 1986 and there was no one in line but it went 91%. Almost all votes went to Democrats.
In presidential elections, the President gets vastly more votes than other candidates because the Presidential campaign pays and the others don't.
