Sen. Grassley said on C-SPAN this morning that today each senator gets 30 min., tomorrow they get 20 min..
On Thurs., I believe the "witnesses" get their time, then to go back to senators' questions. If necessary, they will go through the weekend. It doesn't end until every senator has asked all of his/her questions.
At the end of this hearing, D.C. will end up containing the biggest pile of excrement known to man.
And that doesn't even count all the stalling and delaying tactics the Dims will employ. They will stretch these hearings out for as long as they can and continue to assail President Bush, hoping that dragging his approval down will erode support for Roberts. Eventually, the argument they will make, I'm guessing, is that it's far better that those SCOTUS seats remain vacant than to allow a president with "historically low approval numbers" who "showed his lack of judgement and leadership by botching the hurricane relief efforts" make "lifetime appointments" to the court with such "divisive" nominees.
