Because the fact that American voters fall for the line that our elections are the most secure ever despite the overwhelming evidence to the contrary and allow Democrats to steal elections with impunity is one of the most serious manifestations of the Stupidity of the American voter.
I am optimistic that the Democrats have finally overestimated the stupidity of the American voter this time around but it's still up in the air.
The Democrats were arrogant enough that they did not open their primaries to allow other candidates challenge Biden.
