Roberts' rules of order
WIIIAI nails it:
What makes the sight of John Roberts refusing over and over to answer any substantive question is that it reeks of a sense of entitlement. In his mind the default position in this process is that he be confirmed, that is, that unless they can find something seriously wrong with him, they must confirm him, rather than that he must convince them that he is worthy of this job. I think the default position should be rejection, and if he isn’t willing to provide enough information that senators can see how he’d perform in the job, rejection is what it should be.
