A good start but doomed to failure.
1. There must first be an agreement to national standards barring Constitutional issues of states rights (specifically to determine “time and manner” of voting).
2. There must be a desire by those with controlling interests (aka politicians) to have HONEST elections in the first place.
Time and manner must be balanced by the guarantee of a republican form of government, equal protection, and how the actions of one state affects another. Must go to Supreme Court to sort these things out.
So, unless there is first a reset, such as CW2/Revolution 2, then no such proposals will move forward due to gridlock and political polarization.
Ultimately that might be what is required to have honest elections.
I suspect CW2/Rev2 would ultimately cost less treasure and fewer lives than dishonest elections in a country run by dishonest, acquisitive, and craven politicians.
