Of course, elections, even for federal offices, are administered by states, and no two states have exactly the same election laws. So the Texas law you cited may or many not be applicable to North Carolina, where the events which are the subject of this thread occurred.
I would have to say that Texas now probably has one of the more fair and honest election laws in the country, and you don't generally hear too many complaints about it.
But no matter how fair and decent the law is on paper, any state requires courageous, fair and decent people supervising the election in order to minimize fraud and cheating. Texas probably had similar laws when Lyndon Johnson was able to abuse the system back in 1948 when he cheated his way to the US Senate, which became his eventual springboard to the presidency.
I taught election law for ten years.
After the fiasco in Florida, in 2000, federal laws were passed to reconcile election laws between the states, so election laws between states are now similar. When the new laws were passed, states were required to change their laws to coincide with the federal ones. Those were enormous changes and I was in the middle of that as I had to learn those new laws to teach those new methods. Those laws included the beginning of Provisional Ballots.
Anyway, election laws between the states are not that different now.
What is new and I think will continue to happen, is, states deciding to go with all mail ballots - no voting precincts anymore. That saves millions of dollars for every county/parish. There won’t be any transportation to voting precincts because voters will vote by mail.
“Texas probably had similar laws when Lyndon Johnson was able to abuse the system back in 1948 when he cheated his way to the US Senate, which became his eventual springboard to the presidency.”
Back them, we did not have similar laws compared to now and election judges/clerks were poorly trained, if at all, to hold elections. As time went on, election laws were passed to make elections equal between the counties and to put in place laws that would prevent voter fraud. Johnson could not do today what he did back then.
