It's in Fornicalia's constitution, but not the federal charter.....Same applies to term limits.
Howerver, if enough states decertify their results, it's at least arguable that the current regime hasn't the 270 EVs to be legitimate, which is another can of worms altogether.
The electoral votes are cast. The states can't go back on their own and change it. That would amount to a recall that is not intended or defined in the Constitution.
The Supreme Court, on the other hand, might have a much tougher call on it. There are zero provisions in the Constitution for where we are today: an illegitimate president put in power by a fraudulent election, effectively a coup.
But the Constitution only requires that the electoral votes are certified and delivered to the President of the Senate. Beyond that, the Electoral Count Act tells the Congress what to do next. Unless the Court had taken a case before the vote, or if the congressional vote, itself, was handled unconstitutionally, there's no way the Supreme Court could come back now and toss the election.
What needs to come from the audits are criminal charges and hard time against any vote counter, poller, or any other person who violated all those laws that Smokin' OP keeps quoting, including any governor or secretary of state or other state politician who violated the US or their state constitution in executing their state election process.
We can change the president on January 20, 2025 but, until then, Jill Biden remains president - at least until Kamala Harris replaces her.
