The cable news channels are using the Kagan confirmations as airtime filler. This is equivalent to watching a world cup game where one side will stand on the sidelines after being allowed to build a brickwall that completely covers their goal. Then the winner will be decided by about sixty fans of Kagan side (democratic senators). Nothing will happen but meaningless talk and grandstanding and then Kagan will be confirmed.
The only supreme court nominee who got to this point who was rejected was Robert Bork
Kagan has no background that can be used to reject her and the approval process is just a majority vote which the Democrats have.
