Go to Statistica for national voter registration. Note that it is fairly steady with a little increase for population growth. In 2016 it peaked and had a small decline in 2018. In 2016 it was about 157 Million. They say 155 Million voted for Trump and Biden. Probably about 3 Million for a third party. They claim (USA Today) that there were about 214 Million registered for the 2020 election. That would be a 36% spike in voter registration from its peak in 2016. That is about 57 Million more registered voters. Not likely. Looking at the enthusiasm gap; Trump may have brought 20 Million more to be registered, but Biden would have added little or none. Well short of the 57 Million. We are still only looking at the tip of the voter fraud iceberg.
I suspect right there is the bottom line.
