As pointed out earlier, here in Australia at least we have the Australian Electoral Commission
(AEC) - the independent
federal agency in charge of organising, conducting and supervising federal Australian elections, by-elections and referendums.
What happens in Tasmania, also happens in the Northern Territory, 1000s of miles away, in exactly the same way.
It covers postal ballots, counting rules, invalid voting rules, challenges to results etc. All are uniform.
You cannot count postal votes in Queensland that arrive 3 days after the election, etc, etc, but not do it in other states - which is the current loopy American system.
I cannot comprehend why the USA does not have similar uniformity. It is not that hard.
That Texas nonsense of having just ONE approved place to lodge absentee votes, in a city of 5 million people is quite insane. It again served the purpose of disenfranchising poor and black voters etc, and in 2020 that Jim Crow type stuff should have long been stamped out. It clearly has not been, as some States still call the shots to some extent, making it hard for some folks to lodge votes in person.
The Voting Rights Act of 1965 ended legally sanctioned state barriers to voting for all federal, state and local elections. It also provided for federal oversight and monitoring of counties with historically low minority voter turnout.
Years of enforcement have been needed to overcome resistance, and additional legal challenges have been made in the courts to ensure the ability of voters to elect candidates of their choice.
For instance, many cities and counties introduced at-large election of council members, which resulted in many cases of diluting minority votes and preventing election of minority-supported candidates.
In 2013, the Roberts Court removed the requirement established by the Voting Rights Act that Southern states needed Federal approval for changes in voting policies. Several states immediately made changes in their laws restricting voting access.
