This week the Supreme Court struck down a significant federal law. The law was popular when it was enacted, not that long ago, but times have quickly changed and we’re in a different world. By a 5-4 vote, reflecting the usual right/left split, the Court decided that it was time for that law to go. The Court invoked federalism to get there, reasoning that the federal government was overreaching into an area traditionally regulated by the states that was appropriately reserved to the states. And so the power has been returned to the states, at least for now.
