That's because the hearings are meaningless at this point.
If the hearings actually revealed anything important about a candidate's philosophy, you might have a point. But the dog and pony show that is essentially a PR show for committtee members reveals almost nothing about the candidate and everything about how the senators want their constituents back home to see them.
You make a great point.
That was absolutely NOT the case with the Roberts hearings. We learned more about his judicial philosophy in one 44 second clip than in 50 written opinions.
