Well it's funny you say that actually, so, are problems like border security, spending, inflation, fuel prices and so only applicable when Trump was in office or do they apply to your guy to?Let's assume for a minute that your repeated view is correct. That mail in voting causes such indefensible chain of custody and election integrity issues that it makes the 2020 election of Joe Biden illegitimate.
Following your logic, wouldn't that mean the 2016 election of that President was also illegitimate as mail in voting was widely used and over 33 million mail in votes were cast in that election?
Or are the problems with mail in voting only applicable, when your guy loses?
