An awareness of its existence, and a knowledge of where to find it, and what it, roughly, is about, though... (oh, and the common sense, when seeing a question like that, of finding out what it is first and talking later)... that should really be expected.
But thats exactly what I mean; I didn't know of it, and I'm sure a round robin of many former Senators would also cause some blank faces
But it's there to be
found and understood as one readies themselves with the Constitution and Senate rules
Perhaps I should have been asked such questions during my nomination but there you go....
If this is a new trend I hope it is asked of all future nominees and during Senate races.
