I looked all around and did not see a thread that discussed the actual hearings. So here goes.
Today the hearings started at noon time, and are being shown on CSPAN, etc. One major agenda item for today is for the US Senators to present opening
statements, and as stated by MSNBC,

Hearings start for Supreme Court top nominee
Democrats vow tough questions, but few obstacles expected for Roberts
MSNBC

the partisan lines are quickly being drawn. Kennedy and Biden made it pretty obvious that even if Roberts walked on water, they would vote against
him.
A side note, I was flabbergasted to learn that Ted Kennedy has been on the Judiciary Committee since
1963! Time for some new blood on some of
these committees, IMO.
