Is ObamaCare constitutional?

Is ObamaCare constitutional? "If you ask any constitutional law professor whether Congress can do something, the answer is always yes," says Randy Barnett. But Mr. Barnett, who teaches legal theory at Georgetown, isn't just any law professor. A self-described "radical libertarian," he is the author of a 2004 book, "Restoring the Lost Constitution," that argues for a fundamentally new approach to jurisprudence.

One of America's leading libertarian legal scholars handicaps whether the Supreme Court will find ObamaCare's insurance mandate constitutional.
