No! 2/3rds is needed for treaties and constitutional amendments. Only a majority is needed to confirm an appointee. If McCain can organize 41 GOPers to filibuster then he can stop the nomination from proceeding, but I doubt he could get 20. Of course if things had turned out we’d have the majority but Akin and Mourdock killed that as did losing in Dakota and Montana and Mass.That would have been 3 pickups and two holds. Alas it was not meant to be, still it’s nice to see McCain show a biy of the old fire.
For treaties it is 2/3 of members present IIRC.
Please advise whether or not the Constitution of the United States Article II, Section 2 reads (more-a-less) as follows:
The President shall have Power, by and with the Advice and Consent of the Senate, to make Treaties, provided two thirds of the Senators present concur.
