As U.S. lawmakers work to draft national health care legislation, some state lawmakers are scrambling to draft “opt-out” legislation for their states. Arizona is already scheduled to have an initiative on the 2010 ballot that, if passed, would allow the state to opt out of any federal health care plan. Similar initiatives may also appear on the 2010 ballots in Indiana, Minnesota, New Mexico, North Dakota, and Wyoming.

Some state legislators say they worry that a government-mandated program will effectively eliminate their traditional role in regulating health insurers — an important power base. Others raise constitutional concerns. “The real goal of national health insurance exchange isn’t competition — it’s a federal power grab that flies in the face of the Tenth Amendment,” says Wisconsin state Rep. Leah Vukmir, a Republican.

The Tenth Amendment ensures that “the powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people.” It’s the same constitutional roadblock Franklin D. Roosevelt ran into during the Great Depression when he tried to ram through the first round of recovery programs under the New Deal. In a series of rulings, the U.S. Supreme Court found the National Recovery Act, the Agricultural Adjustment Act and several other recovery programs unconstitutional.
