Health: Trump packed the Supreme Court with originalists, not conservatives. Under the Constitution, as originally written, election law is totally in the hands of the states. If the state’s highest courts have not found the election to be fraudulent, it isn’t for a federal court to get involved.
So he moves to Florida and mopes. Considering the Republican party did well in the election (Trump trailed the ticket, and that suggests he hurt the Republicans more than he helped), he’ll probably retire. The Republicans will keep much of Trump’s populism, but will tweet lightly and in 2025 will have solid control of the federal government (Congress, Executive and Courts).
