Nuff Said.
Remember Junior high? Remember how wrong and stupid you thought it was when your "civics" class learned about the Filibuster?
A super-majority is dictated in the Constitution for specific instances, and the appointment of judges is not one of them.
The founders knew what they were doing.
Whereas in the case of the advise and consent, they left it up to the Senate. Is there anything in the Constitution about Judiciary committee votes? Or nominees getting bottled up in committees? Didn't think so.
