“Congress desperately needs to take back its power to legislate.”
You need to understand that Congress is perfectly happy to let the administrative branch do the controversial rulemaking. That way the critters can’t be held responsible for unpopular mandates. The same thinking holds with states which are perfectly happy to let the feds make the hard rules. Each group is passing the buck to reach the unelected, unaccountable bureaucracy, aka Deep State, exactly as planned for decades.
I am certainly aware of that. All three branches of the federal government had a hand in concentrating power in the executive branch, but Congress bears more responsibility than anyone other than, perhaps, the voters themselves.
