The Constitution gives the power to elect electors to the States. One might even be able to make an argument that a State could chose to Rock, Paper, Scissors to determine how to select electors. It’s up to the people of each State to hold their leaders accountable. Do I think this election was stolen? Absolutely, but I hold no standing in any of the stolen States.
PA wanted to redo their electors but have been out of session the last month.
That is a simplistic argument being made by Rand Paul and others. If it was true, and the Senate and House had no say over how the electors were chosen then there would be no role for the federal courts related to state elections. And there would be no basis for federal laws like the voting rights act.
But federal courts regularly issue opinions and injunctions that control how states run their presidential elections. They are involved in just about every detail of the election process, and federal courts in this election issued multiple injunctions related to how the states selected their electors.
Don't be fooled by the talking points of politicians.
