Sorry that was all ended after the civil war federal law trumps states rights and seeing as sloppiness state to state can lead to irregular Federal elections it's required for the federal government to make sure that doesn't happen
Think Chicago 1960 Richard Nixon won that election but rigged voting in Chicago caused Kennedy to win Illinois and therefore the election Nixon didn't want to contest it he preferred not to pull an Al Gore 2000.
Rigged voting in Georgia 2020 caused Trump to lose that election to Biden if the states can't manage their own affairs it's required to federal government step in. It's funny how I used to think of myself as a Confederate but it seems that these days it's the Democrats taking on that role just think Minnesota and Tim Walz.
