But one eminent conservative legal scholar says: Dream on. Harvard Law professor Charles Fried, who was solicitor general under President Ronald Reagan, believes the constitutional argument against ObamaCare is so weak that even the Roberts court will reject it.
The legal challenges argue that it rests on an unconstitutional provision: the requirement that every individual either buy health insurance or pay a fine. The chief proponent of this theory is Georgetown University law professor Randy Barnett, who says the mandate goes beyond Congress' power to regulate interstate commerce.
"Never in this nation's history has the commerce power been used to require a person who does nothing to engage in economic activity," writes Barnett. "Therefore, no decision of the Supreme Court has ever upheld such a claim of power."
The argument gained new credence when two different federal judges ruled the mandate unconstitutional (though two others disagreed). In January, District Judge Roger Vinson concluded, "If Congress can penalize a passive individual for failing to engage in commerce, the enumeration of powers in the Constitution would have been in vain."
Fried, who made an unexpected endorsement of Obama in 2008, disagrees -- and says he is the norm among his ideological kindred in the academy. "I have not met any scholars who teach constitutional law and are members of The Federalist Society who think it's unconstitutional," he told me by phone, referring to the libertarian-conservative legal group.
His case is simple: Health insurance is commerce. Congress has the power to regulate commerce. Because it has that power, it may also select the means to achieve its goals. The individual mandate is a permissible way to advance the purpose of expanding access to health care.
His interpretation, says Fried, "goes back to John Marshall," a delegate to the Constitutional Convention and the most important chief justice in Supreme Court history. It was Marshall who definitively explained Congress' right "to make all laws which shall be necessary and proper for carrying into execution" its specified powers.
