Coburn should ask Kagin about her opinions and translations of many of Madison’s Federalist writings where Madison said that the Federal government’s role was to be limited.
The question I'd like posed is to describe the 2nd amendment "Miller" case. Not to say whether it was rightly decided, or should be upheld, etc. - just describe what it stands for. "Brief the case," if you will. Who were the parties? What were the facts, decision below, and ruling of the Supreme Court. I'd even give the nominee a couple days to read the case and prepare notes. If a potential judge can't accurately brief a 3 page opinion, that candidate has no business being behind the bench.
