IF we regain control of the House and Senate in 2022 and IF ( and this is a big IF ) it can be proved that Biden/Harris were aware of it, it seems to me that is grounds for impeachment. But of course you need Republicans with a set of balls to do anything about it. Marjorie Taylor Greene from GA has a bigger set than McConnell will ever have ( if he has any at all )
His balls are only as big as it takes for him to enrich himself.
Biden bragged about the unprecedented scale of the voter fraud machine he’d inherited ... so he’s provably aware.
Of course Republicans with balls are as rare as Democrats with good ethics.
