I agree with the majority of posters here that say “that horse got out of the barn a long time ago” regarding the unconstitutional abuse of powers by the federal government.
But the reason dates back to the supreme court commerce clause case Wickard v. Filburn, marking the most dramatic expansion of federal powers in our history: “the Supreme Court abruptly reversed its interpretation of the U.S. Constitution and began to rule in a string of cases that the “Commerce Clause” of the Constitution empowered Congress to regulate all aspects of life in the United States, even commerce within a state, and even activity that is strictly speaking not commerce at all.”
So it dates back to the New Deal and the creation of a new, dramatic expansion of federal government power, thanks to the supreme court (and indirectly attributable to Roosevelt).

This horse is not out not the barn yet. Constitutional conservatives should vote no on RUNOcare and push for a clean repeal bill.
