Every single Supreme Court nominee is. They had many boards with Alito and Roberts before the Senate Hearings. Did you not know this?
That is why you gotta concentrate on cases that have already been decided. You tell the nominee that you want only yes or no answers and that you will cut them off if they quibble or equivocate. Such as:
Given the writing of the Constitution at the time, was Dred Scott v. Sandford decided correctly?
Wong Kim Ark v. United States declared Ark to be a citizen under the 14th Amendment. Given that Ark's parents were legally within the United States at the time of his birth, would it now be proper to re-visit Ark [given much the same facts] if a plaintiff's parents are illegal?
If the previous answer is no, does Ark cover it under stare decisis?
Wong Kim Ark v. United States declared Ark to be a citizen under the 14th Amendment. Given that, would it now be proper to re-visit Ark [vis-a-vis natural-born citizenship] if a candidate for POTUS had dual citizenship at the time of his birth?
If the previous answer is no, does Ark cover it under stare decisis?
Was Kelo v. New London [eminent domain case] correctly decided???
