The constitution gives legislatures the power to choose the manner in which electors are chosen.... by the legislature voting themselves, or by the vote of the citizens, or by flipping a coin etc.
These legislatures chose to give up the legislature picking the electors, and gave it to the citizens to choose.
But the legislature did NOT approve or vote on the changes.
If they did, show me. Otherwise just stop the bullshit.
The duty was to decide if their legislature was going to choose the electors, if not, then who? All of our different legislatures chose the citizens vote would determine and choose their electors. Thats the "manner" in which they are chosen that the constitution speaks of.... once this is chosen, the constitutional requirement is fulfilled.
The US constitution does not govern the finer details of how an election process is done within each state.
The Texas case has no Constitutional standing.
Michiganders etc. can argue about their own processes not being followed in their own State courts.... but the US constitutional mandate of their legislatures choosing the "manner" of electing their electors, thru the citizen's vote, instead of the legislature's vote, was fulfilled, in my opinion.
