I have posted this many times on this board. However, like others have said, they cant do this with the gonzalez nomination. First of all, they have to realize gonzalez is about the best they can get out of this president. To reject him, they are assured of getting an even more right wing nominee to follow him. Secondly, Gonzalez won his AG confirmation vote 60-36 (Not sure which 4 senators did not vote). Among the democrats voting for him were Lieberman (CT), Landrieu (LA), Pryor (AR), Nelson (FL), Nelson (NE), and Salazar (CO). All but Nelson (FL) are part of the so called "Gang of 14" who signed the no filibuster agreement unless under extreme circumstances. They are going to have a hard time explaining why they agreed to confirm him for AG, but not its an extreme circumstance and vote to filibuster and hold him up from a supreme court spot.
On a side note, how can you be a United States Senator and NOT vote on the attorney general of the United States? What could be more important?
