Honestly, if Trump lost the election due to vote fraud then in many ways he has nobody but himself to blame. During the four years of the Trump administration the Department of Justice did nothing to combat vote fraud. Allegations of fraud were made about the 2016 election and the 2018 election but no investigations were launched, no charges were levied or people arrested, no trials or convictions. Had a major effort been made to deal with the fraud then the chances of it occurring on the levels alleged during the 2020 election could have been greatly reduced. But instead nothing was done and we get to live with the results for the next four years.
I certainly blame the perpetrators of election fraud.
Perhaps if we ever get a conservative President again, his top priority will be to fight election fraud. I think Republicans have been asleep at the wheel for the last 60 years. They’ve been focused on little things like defeating the Soviet Union, border control, stopping Muslim terrorism in the US, etc.
