If we go back to the Brennan Center study conducted in 2107, they discovered that overall voting fraud in the US is between 0.00004% and 0.0009%. So, it is highly unlikely that an increase in voting by mail is going to adversely affect the upcoming 2020 presidential election regardless of any claims made to the contrary.
Today, figures like My Pillow Guy, Mike Lindell, are continuing to hold barely attended conferences claiming that he possessed “enough evidence to put everybody in prison for life, 300-some million people” for their part in the alleged 2020 election fraud. He has yet to come forward with that wealth of damning evidence.
And he is far from the only one convinced of this, as a recent Reuters/Ipsos opinion poll worryingly showed that, according to their figures, a staggering 53% of Republicans still believe 2020 election was stolen from Trump, and even 3% of Democrats believe that as well.
