Only the US Supreme Court can put a stop to this crime, and turn the election over to the House.
Plan A: Supreme Court
Plan B: Some variation of Martial Law to stop the clock, throw the crooks in jail so they can’t get involved in the process (that includes, the governor, secretary of state, and any other state officials that enabled the fraud). Then have outsiders come in and verify signatures and chain of custody to the extent possible.
Sadly, the Supreme Court is likely to use Rudy’s constitutional argument to not rule on it at all.
May just point out the constitutional authority is in the state legislators.
