Bill Barr, the Attorney General appointed by Trump to investigate claims of voter fraud, repeatedly told President Trump that he saw no evidence of fraud sufficient to overturn the election. He also later added later that that in a year and half he hadn’t seen anything to change his mind on that either.
We must remember that Barr was Trump’s loyal Attorney General. Many critics felt he was so loyal he allowed the Justice Department to act as Trump’s personal law firm. He said there was zero evidence that the voting machines had been tampered with even though such allegations had been made in such a sensational manner that there was a large part of the American population that believed they were evidence of systemic problems in the voting system. They believed their votes did not count. They believed that not because they were given any evidence of that, they believed that because members of “their side” told them this was the case, even though it was not true. As Barr said to Congress, “this was complete nonsense…and crazy stuff and that they were wasting their time on that and it was doing a great disservice to the country.
Yet a substantial part of the American public believed this “nonsense” and “crazy stuff.” And they still do. That is what happens when a credulous populace is confronted with unsubstantiated claims by their leader. They believe their leader no matter how nonsensical his claims and in this case, they were indeed nonsensical.
Trump continued to spread these false allegations at least a dozen times after his Attorney General told him there was no basis in fact for those allegations. And he has continued to do that. None of that mattered to Trump. All that matter is what he believed even though there was no evidence to support those beliefs. Trump has never been concerned about evidence. He just cares about belief. And whatever suits him and what he wants, he believes. That is what he thinks the truth is—i.e. what is good for Donald Trump.
