In December, 2020, Trump's Attorney General William Barr declared the U.S. Justice Department had uncovered no evidence of widespread voter fraud that could change the outcome of the 2020 election. Prior to that, every Secretary of State, Republican and Democrat alike certified their state's election results. All the judges, even Trump appointed ones, ruled against Trump's 60 some court challenges claiming election fraud. We've since learned that Trump tried to force his appointees at the DOJ to announce that the election was corrupt. They refused to lie for him. AG Barr didn't fall for Trump's con either and resigned his position later that month. Trump wants you to believe that he will be reinstated as president on Aug 13, 2021. Don't fall for the con.
None of that changes the essential truth of what I said.
You rely on the testimony of other people. You're taking it on faith.
That doesn't make you wrong. It simply means you don't know with absolute certitude, and likely never will.
