Barnett on the Supreme Court Confirmation Hearing

Cato senior fellow Randy Barnett has a piece in the Wall Street Journal on the Senate's confirmation hearing for Obama's nominee to the Supreme Court.  Excerpt:

Supreme Court confirmation hearings do not have to be about either results or nothing. They could be about clauses, not cases. Instead of asking nominees how they would decide particular cases, ask them to explain what they think the various clauses of the Constitution mean.

Does the Ninth Amendment protect judicially enforceable unenumerated rights? Does the Necessary and Proper Clause delegate unlimited discretion to Congress?
